The TMUX1511 is a complementary metal-oxide
semiconductor (CMOS) switch. 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.

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.

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.

8 Detailed Description
8.1 Overview
The TMUX1511 is a high speed 1:1 (SPST) 4-channel switch with powered-off protection up to 3.6 V. 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.

8.3 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.

Feature Description (continued)
8.3.3 1.8 V Logic Compatible Inputs
The TMUX1511 has 1.8-V logic compatible control inputs. 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.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. 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.

9.2.1.2 Detailed Design Procedure
The TMUX1511 can be operated without any external components except for the supply decoupling capacitors.
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

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.

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°. Refer to Improve Stability Issues with Low CON
Multiplexers for more information on calculating the phase margin vs. percent overshoot.

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.

11 Layout
11.1 Layout Guidelines
When a PCB trace turns a corner at a 90° angle, a reflection can occur. 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.

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. Some key considerations are:

Layout Guidelines (continued)
Decouple the VDD pin with a 0.1-μF capacitor, placed as close to the pin as possible. 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.
