The TMUX1511 offers 1:1 SPST switch configuration with 4 independently controlled channels. Wide operating supply of 1.5 V to 5.5 V allows for use in a broad array of applications from servers and communication equipment to industrial applications. The device supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins and can pass signals above supply up to VDD x 2, with a maximum input/output voltage of 5.5 V. 1 Wide Supply Range: 1.5 V to 5.5 V Low On-Capacitance: 3.3 pF Low On-Resistance: 2 Ω High Bandwidth: 3 GHz -40°C to +125°C Operating Temperature 1.8 V Logic Compatible Supports Input Voltage Beyond Supply Integrated Pull Down Resistor on Logic Pins Bidirectional Signal Path Fail-Safe Logic Powered-off Protection up to 3.6 V – Pinout compatible to SN74CBTLV3126 – Pinout compatible (logic variant) of SN74CBTLV3125 Fail-Safe Logic circuitry allows voltages on the logic control pins to be applied before the supply pin, protecting the device from potential damage. All logic control inputs have 1.8 V logic compatible thresholds, ensuring both TTL and CMOS logic compatibility when operating in the valid supply voltage range. 2 Applications • • • • • • • • • • • • Powered-off Protection up to 3.6 V on the signal path of the TMUX1511 provides isolation when the supply voltage is removed (VDD = 0 V). Without this protection feature, switches can back-power the supply rail through an internal ESD diode and cause potential damage to the system.

The on-resistance varies with input voltage and supply voltage. The symbol RON is used to denote on-resistance. The measurement setup used to measure RON is shown in Figure 27 . Voltage (V) and current (IDS) are measured using this setup, and RON is computed as shown below with RON = V / ISD: V ISD Sx Dx VS Figure 27. On-Resistance Measurement Setup 7.2 Off-Leakage Current Source off-leakage current is defined as the leakage current flowing into or out of the source pin when the switch is off. This current is denoted by the symbol IS(OFF). Drain off-leakage current is defined as the leakage current flowing into or out of the drain pin when the switch is off. This current is denoted by the symbol ID(OFF). The setup used to measure both off-leakage currents is shown in Figure 28.

Wide operating supply of 1.5 V to 5.5 V allows for use in a broad array of applications from servers and communication equipment to industrial applications. The device supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins. The wide bandwidth of this switch allows little or no attenuation of the high-speed signals at the outputs to pass with minimum edge and phase distortion as well as propagation delay. The select (SELx) pins are active-high logic pins that control the connection between the source (Sx) and drain (Dx) pins of the device. Each channel of the TMUX1511 can be controlled independently through the associated select pin, or all four select pins can be tied together for simultaneous control of all channels with a single GPIO. Fail-Safe Logic circuitry allows voltages on the logic control pins to be applied before the supply pin, protecting the device from potential damage. All logic control inputs have 1.8V logic compatible thresholds, ensuring both TTL and CMOS logic compatibility when operating in the valid supply voltage range. Powered-off protection up to 3.6 V on the signal path of the TMUX1511 provides isolation when the supply voltage is removed (VDD = 0 V). Without this protection feature, the system can back-power the supply rail through an internal ESD diode and cause potential damage to the system. 8.2 Functional Block Diagram TMUX1511 SEL1 SEL4 S1 S4 D1 D4 SEL2 SEL3 S2 S3 D2 D3 *Internal 6MO Pull-Down on Logic Pins 8.3 Feature Description 8.3.1 Bidirectional Operation The TMUX1511 conducts equally well from source (Sx) to drain (Dx) or from drain (Dx) to source (Sx). Each channel has very similar characteristics in both directions and supports both analog and digital signals. 8.3.2 Beyond Supply Operation When the TMUX1511 is powered from 1.5 V to 5.5 V, the valid signal path input/output voltage ranges from GND to VDD x 2, with a maximum input/output voltage of 5.5 V. Example 1: If the TMUX1511 is powered at 1.5V, the signal range is 0 V to 3 V. Example 2: If the TMUX1511 is powered at 3V, the signal range is 0 V to 5.5 V. Example 3: If the TMUX1511 is powered at 5.5V, the signal range is 0 V to 5.5 V. Other voltage levels not mentioned in the examples will support Beyond Supply Operation as long as the supply voltage falls within the recommended operation conditions of 1.5 V to 5.5 V.

Regardless of the VDD voltage, the control input thresholds remain fixed, allowing a 1.8-V processor GPIO to control the TMUX1511 without the need for an external translator. This saves both space and BOM cost. For more information on 1.8 V logic implementations refer to Simplifying Design with 1.8 V logic Muxes and Switches. 8.3.4 Powered-off Protection Powered-off protection up to 3.6 V on the signal path of the TMUX1511 provides isolation when the supply voltage is removed (VDD = 0 V). When the TMUX1511 is powered-off, the I/Os of the device remain in a high-Z state. Powered-off protection minimizes system complexity by removing the need for power supply sequencing on the signal path. The device performance remains within the leakage performance mentioned in the Electrical Specifications. For more information on powered-off protection refer to Eliminate Power Sequencing with Powered-off Protection Signal Switches 8.3.5 Fail-Safe Logic The TMUX1511 has Fail-Safe Logic on the control input pins (SELx) which allows for operation up to 5.5 V, regardless of the state of the supply pin. This feature allows voltages on the control pins to be applied before the supply pin, protecting the device from potential damage. Fail-Safe Logic minimizes system complexity by removing the need for power supply sequencing on the logic control pins. For example, the Fail-Safe Logic feature allows the select pins of the TMUX1511 to be ramped to 5.5 V while VDD = 0 V. Additionally, the feature enables operation of the TMUX1511 with VDD = 1.5 V while allowing the select pins to interface with a logic level of another device up to 5.5 V. 8.3.6 Low Capacitance The TMUX1511 has very low capacitance in both the ON and OFF states on the source and drain pins. The low capacitance specification allows the TMUX1511 to be used in applications such as sample & hold circuits, and in the feedback path of an operation amplifier. Low capacitance helps to reduce large overshoots and ringing of an amplifier circuit when the switch is connected to the feedback network. Additionally, low capacitance improves system settling time by reducing the switch time constant formed by the On-resistance and On-capacitance. For more information on the benefits of low capacitance refer to Improve Stability Issues with Low CON Multiplexers. 8.3.7 Integrated Pull-Down Resistors The TMUX1511 has internal weak pull-down resistors (6 MΩ) to GND to ensure the logic pins are not left floating. This feature integrates up to four external components and reduces system size and cost. 8.4 Device Functional Modes The select (SELx) pins are active-high logic pins that control the connection between the source (Sx) and drain (Dx) pins of the device. The TMUX1511 has internal weak pull-down resistors (6 MΩ) to GND so that it powerson with the switches disabled. When a given select pin of the TMUX1511 is pulled high, the corresponding switch conducts from the source to drain. When any of the select pins are pulled low, the corresponding switch is in an open state (HI-Z). Each channel of the TMUX1511 can be controlled independently through the associated select pin, or all four select pins can be tied together for simultaneous control of all channels with a single GPIO. 8.5 Truth Tables Table 1 shows the truth table for the TMUX1511.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The TMUX15xx family offers high-speed system performance across a wide operating supply (1.5 V to 5.5 V) and operating temperature (-40°C to +125°C). The TMUX1511 supports a number of features that improve system performance such as 1.8 V logic compatibility, input voltages beyond supply, Fail-Safe Logic, and Powered-off Protection up to 3.6 V. These features make the TMUX15xx a family of protection multiplexers and switches that can reduce system complexity, board size, and overall system cost. 9.2 Typical Application 9.2.1 Protocol / Signal Isolation One useful application to take advantage of the TMUX1511 features is isolating various protocols from a possessor or MCU such as JTAG, SPI, or standard GPIO signals. The device provides excellent isolation performance when the device is powered. The added benefit of powered-off protection allows a system to minimize complexity by eliminating the need for power sequencing in hot-swap and live insertion applications.

The device has internal weak pull-down resistors (6 MΩ) to GND so that it powers-on with the switches disabled. All inputs signals passing through the switch must fall within the recommend operating conditions of the TMUX1511 including signal range and continuous current. For this design example, with a supply of 3.3 V, the signals can range from 0 V to 3.3 V when the device is powered. This example can also utilize the Powered-off Protection feature and the inputs can range from 0 V to 3.3 V when VDD = 0 V. The max continuous current can be 25 mA. Due to the voltage range and high speed capability, the TMUX1511example is suitable for use in JTAG and SPI applications beyond the 100 MHz maximum in a typical application. 9.2.1.3 Application Curves Two important specifications when using a switch or multiplexer to pass signals are the device propagation delay and skew. 70 60 Propagation Delay Time (pS) 50 40 30 Skew 20 10 0 1.5 2 2.5 3 3.5 4 4.5 Supply Voltage (V) 5 5.5 6 D018 Figure 41. Propagation Delay and Skew Measurement 9.2.2 Transimpedance Amplifier Feedback Control Switches and multiplexers are commonly used in the feedback path of amplifier circuits to provide configurable gain control. By using various resistor values on each switch path the TMUX1511 allows the system to have multiple gain settings. An external resistor, or utilizing 1 channel always being closed, ensures the amplifier isn't operating in an open loop configuration. A transimpedance amplifier (TIA) for photodiodes is a common circuit that requires gain control using a multi-channel switch to convert the output current of the photodiode into a voltage for the MCU or processor. The leakage current, capacitance, and charge injection performance of the TMUX1511 are key specifications to evaluate when selecting a device for gain control. 0.1µF VI/O VDD VDD Processor SEL1 SEL2 SEL3 SEL4 1.8V Logic I/O RF_1 Digital Processin g RF_2 RF_3 RF_4 VDD VDD IPD + OP AMP Gai n / Fil ter Network ADC Figure 42.

Table 3. Design Parameters PARAMETERS VALUES Supply (VDD) 5V Input / Output signal range 0 µA to 10 µA Control logic thresholds 1.8 V compatible 9.2.2.2 Detailed Design Procedure Photodiodes commonly have a current output that ranges from a few hundred picoamps to tens of microamps based on the amount of light being absorbed. The TMUX1511 has a typical On-leakage current of less than 10 pA which would lead to an accuracy well within 1% of a full scale 10 µA signal. The low ON and OFF capacitance of the TMUX1511 improves system stability by minimizing the total capacitance on the output of the amplifier. Lower capacitance leads to less overshoot and ringing in the system which can cause the amplifier circuit to go unstable if the phase margin is not at least 45°.

Capacitance vs Frequency Figure 43. On-Leakage vs Source or Drain Voltage 10 Power Supply Recommendations The TMUX1511 operates across a wide supply range of 1.5 V to 5.5 V. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the devices. Power-supply bypassing improves noise margin and prevents switching noise propagation from the VDD supply to other components. Good power-supply decoupling is important to achieve optimum performance. For improved supply noise immunity, use a supply decoupling capacitor ranging from 0.1 μF to 10 μF from VDD to ground. Place the bypass capacitors as close to the power supply pins of the device as possible using low-impedance connections. TI recommends using multi-layer ceramic chip capacitors (MLCCs) that offer low equivalent series resistance (ESR) and inductance (ESL) characteristics for power-supply decoupling purposes. For very sensitive systems, or for systems in harsh noise environments, avoiding the use of vias for connecting the capacitors to the device pins may offer superior noise immunity. The use of multiple vias in parallel lowers the overall inductance and is beneficial for connections to ground planes.

A reflection occurs primarily because of the change of width of the trace. At the apex of the turn, the trace width increases to 1.414 times the width. This increase upsets the transmission-line characteristics, especially the distributed capacitance and self–inductance of the trace which results in the reflection. Not all PCB traces can be straight and therefore some traces must turn corners. Figure 45 shows progressively better techniques of rounding corners. Only the last example (BEST) maintains constant trace width and minimizes reflections. BETTER BEST 2W WORST 1W min. W Figure 45. Trace Example Route the high-speed signals using a minimum of vias and corners which reduces signal reflections and impedance changes. When a via must be used, increase the clearance size around it to minimize its capacitance. Each via introduces discontinuities in the signal’s transmission line and increases the chance of picking up interference from the other layers of the board. Be careful when designing test points, throughhole pins are not recommended at high frequencies. Do not route high speed signal traces under or near crystals, oscillators, clock signal generators, switching regulators, mounting holes, magnetic devices or ICs that use or duplicate clock signals. Avoid stubs on the high-speed signals traces because they cause signal reflections. Route all high-speed signal traces over continuous GND planes, with no interruptions. Avoid crossing over anti-etch, commonly found with plane splits. When working with high frequencies, a printed circuit board with at least four layers is recommended; two signal layers separated by a ground and power layer as shown in Figure 46. Signal 1 GND Plane Power Plane Signal 2 Figure 46. Example Layout The majority of signal traces must run on a single layer, preferably Signal 1. Immediately next to this layer must be the GND plane, which is solid with no cuts. Avoid running signal traces across a split in the ground or power plane. When running across split planes is unavoidable, sufficient decoupling must be used. Minimizing the number of signal vias reduces EMI by reducing inductance at high frequencies. Figure 47 illustrates an example of a PCB layout with the TMUX1511.

Make sure that the capacitor voltage rating is sufficient for the VDD supply. High-speed switches require proper layout and design procedures for optimum performance. Keep the input lines as short as possible. Use a solid ground plane to help reduce electromagnetic interference (EMI) noise pickup. Do not run sensitive analog traces in parallel with digital traces. Avoid crossing digital and analog traces if possible, and only make perpendicular crossings when necessary. 11.2 Layout Example Wide (low inductance) trace for power Via to GND plane C SEL1 VDD S1 SEL4 D1 S4 SEL2 TMUX1511 D4 S2 SEL3 D2 S3 GND D3 Figure 47.
