TMUX821x 100-V, Flat Ron, 1:1 (SPST), 4-Channel Switches
with Latch-Up Immunity and 1.8-V Logic
1 Features
3 Description
•
The TMUX8211, TMUX8212, and TMUX8213 are
modern high voltage capable analog switches
with Latch-Up immunity. Each device has four
independently controllable 1:1, single-pole singlethrow (SPST) switch channels. The devices work well
with dual supplies, a single supply, or asymmetric
supplies up to a maximum supply voltage of 100 V.
The TMUX821x devices provide consistent analog
parametric performance across the entire supply
voltage range. The TMUX821x family supports
bidirectional analog and digital signals on the source
(Sx) and drain (Dx) pins.

High voltage bidirectional switching
Analog and digital signal switching
Semiconductor test equipment
LCD test equipment
Battery test equipment
Data acquisition systems (DAQ)
Digital multi-meter (DMM)
Factory automation and control
Programmable logic controllers (PLC)
Analog input modules
All logic inputs support logic levels of 1.8 V, 3.3 V, and
5 V and can be connected as high as 48 V, allowing
for system flexibility with control signal voltage. Failsafe logic circuitry allows voltages on the logic pins to
be applied before the supply pin, protecting the device
from potential damage.
The device family provides Latch-Up immunity,
preventing undesirable high current events between
parasitic structures within the device. A Latch-Up
condition typically continues until the power supply
rails are turned off and can lead to device failure.
The Latch-Up immunity feature allows this family of
multiplexers to be used in harsh environments.

Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute maximum ratings do not imply
functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions.
If briefly operating outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not
sustain damage, but it may not be fully functional. Operating the device in this manner may affect device reliability, functionality,
performance, and shorten the device lifetime.
Signal path pins are diode-clamped to the power-supply rails. Over voltage signals must be voltage and current limited to maximum
ratings.
For QFN package: Ptot derates linearly above TA = 70°C by 24.0 mW/°C
For TSSOP package: Ptot derates linearly above TA = 70°C by 10.5 mW/°C

8 Parameter Measurement Information
8.1 On-Resistance
The On-Resistance of the TMUX821x is the ohmic resistance across the source (Sx) and drain (Dx) pins
of the device. The On-Resistance varies with input voltage and supply voltage. The symbol RON is used to
denote On-Resistance. Figure 8-1 shows the measurement setup used to measure RON. ΔRON represents the
difference between the RON of any two channels, while RON_FLAT denotes the flatness that is defined as the
difference between the maximum and minimum value of On-Resistance measured over the specified analog
signal range.

to rise to a 90% final value after the SELx signal has risen (for NC switches) or fallen (for NO switches) to a
50% final value. Turn-Off time (tOFF) is defined as the time taken by the output of the TMUX8211, TMUX8212,
and TMUX8213 to fall to a 10% initial value after the SELx signal has fallen (for NC switches) or risen (for NO
switches) to a 50% initial value. Figure 8-4 shows the setup used to measure tON and tOFF.

8.9 THD + Noise
The total harmonic distortion (THD) of a signal is a measurement of the harmonic distortion, and is defined as
the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency at
the multiplexer output. The On-Resistance of the device varies with the amplitude of the input signal and results
in distortion when the drain pin is connected to a low-impedance load. Total harmonic distortion plus noise is
denoted as THD+N. Figure 8-9 shows the setup used to measure THD+N of the devices.

9 Detailed Description
9.1 Overview
The TMUX8211, TMUX8212 and TMUX8213 are a modern complementary metal-oxide semiconductor (CMOS)
analog switches in quad single-pole single-throw configuration. The devices work well with dual supplies, a
single supply, or asymmetric supplies.

9.3 Feature Description
9.3.1 Bidirectional Operation
The devices conduct equally well from source (Sx) to drain (Dx) or from drain (Dx) to source (Sx). Each signal
path has similar characteristics in both directions.
9.3.2 Flat On-Resistance
The TMUX821x devices are designed with a special switch architecture to produce ultra-flat On-Resistance
(RON) across most of the switch input operating region. The flat RON response allows the device to be used in
precision sensor applications since the RON is controlled regardless of the signals sampled. The architecture
is implemented without a charge pump so no unwanted noise is produced from the device to affect sampling
accuracy.
The flattest On-Resistance region extends from VSS to roughly 5 V below VDD. Once the signal is within 5 V of
VDD the On-Resistance will exponentially increase and may impact desired signal transmission.
9.3.3 Protection Features
These devices offer a number of protection features to enable robust system implementations.
9.3.3.1 Fail-Safe Logic
Fail-safe logic circuitry allows voltages on the logic control pins to be applied before the supply pins, protecting
the device from potential damage. Additionally the fail safe logic feature allows the logic inputs of the mux to be
interfaced with high voltages, allowing for simplified interfacing if only high voltage control signals are present.
The logic inputs are protected against positive faults of up to +48 V in powered-off condition, but do not offer
protection against negative over-voltage condition.
Fail-safe logic also allows the devices to interface with a voltage greater than VDD on the control pins during
normal operation to add maximum flexibility in system design. For example, with a VDD = 15 V, the logic control
pins could be connected to +24 V for a logic high signal which allows different types of signals, such as analog
feedback voltages, to be used when controlling the logic inputs. Regardless of the supply voltage, the logic
inputs can be interfaced as high as 48 V.

9.3.3.2 ESD Protection
All pins support HBM ESD protection level up to ±2 kV, which helps protect the devices from ESD events during
the manufacturing process.
9.3.3.3 Latch-Up Immunity
Latch-Up is a condition where a low impedance path is created between a supply pin and ground. This condition
is caused by a trigger (current injection or over-voltage), but once activated the low impedance path remains
even after the trigger is no longer present. This low impedance path may cause system upset or catastrophic
damage due to excessive current levels. The Latch-Up condition typically requires a power cycle to eliminate the
low impedance path.
In the TMUX821x devices, an insulating oxide layer is placed on top of the silicon substrate to prevent any
parasitic junctions from forming. As a result, the devices are Latch-Up immune under all circumstances by
device construction.
The TMUX821x devices are constructed on silicon on insulator (SOI) based process where an oxide layer is
added between the PMOS and NMOS transistor of each CMOS switch to prevent parasitic structures from
forming. The oxide layer is also known as an insulating trench and prevents triggering of latch up events due
to over-voltage or current injections. The Latch-Up immunity feature allows the TMUX821x to be used in harsh
environments. For more information on Latch-Up immunity, refer to Using Latch Up Immune Multiplexers to Help
Improve System Reliability.
9.3.4 1.8 V Logic Compatible Inputs
The TMUX821x devices have 1.8 V logic compatible control for all logic control inputs. 1.8 V logic level inputs
allows the TMUX821x to interface with processors that have lower logic I/O rails and eliminates the need for an
external translator, which 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.
9.3.5 Integrated Pull-Down Resistor on Logic Pins
The TMUX821x have internal weak Pull-Down resistors to GND to ensure the logic pins are not left floating. The
value of this Pull-Down resistor is approximately 4 MΩ, but is clamped to 1 µA at higher voltages. This feature
integrates up to four external components and reduces system size and cost.

9.4 Device Functional Modes
9.4.1 Normal Mode
In Normal Mode operation, signals of up to VDD and VSS can be passed through the switch from source (Sx)
to drain (Dx) or from drain (Dx) to source (Sx). The select (SELx) pins determine which switch path to turn on,
according to the Truth Table. The following conditions must be satisfied for the switch to stay in the ON condition:
• The difference between the primary supplies (VDD – VSS) must be greater than or equal to 10 V. With a
minimum VDD of 10 V.
• The input signals on the source (Sx) or the drain (Dx) must be between VDD and VSS.
• The logic control (SELx) must have selected the switch.
9.4.2 Truth Tables
Table 9-1, Table 9-2, and Table 9-3 show the truth tables for the TMUX8211, TMUX8212, and TMUX8213,

10 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, as well as validating and testing their design
implementation to confirm system functionality.
10.1 Application Information
The TMUX821x are high voltage switches capable of supporting analog and digital signals. The high voltage
capability of these multiplexers allow them to be used in systems with high voltage signal swings, or in systems
with high common mode voltages.
Additionally, the TMUX821x devices provide consistent analog parametric performance across the entire supply
voltage range allowing the devices to be powered by the most convenient supply rails in the system while still
providing excellent performance.
10.2 Typical Application
A common feature of many PMUs (precision measurement units) is the ability to change current ranges. This
allows for a system defined current clamp when testing devices and reduces possible damage to the PMU and
DUT (device under test). In high voltage PMUs, large relays are often used to enable this switching, but this
comes with the trade-off of size. To reduce system size, a multi-channel high voltage switch can be added to
facilitate this switching with minimal impact to system size and performance. The TMUX821x allows for switching
between multiple current ranges, and has the added flexibility to use multiple channels in parallel for high current
applications.

10.2.2 Detailed Design Procedure
Multiplexing PMU systems enables a small, flexible solution that can be used over a wide range of current
ranges. TI’s high voltage multiplexers offer a size advantage over typical relay solutions while still achieving an
extremely low level of distortion, noise, and leakage. This high voltage multiplexer can be use in tandem with
high voltage operational amplifiers and DACs to create an accurate PMU with excellent signal-to-noise ratio.
In this example application, the TMUX8212 is paired with a high voltage amplifier and a DAC. The DAC
generates an arbitrary voltage signal that feeds into the amplifier. An additional high voltage offset is also fed
into the amplifier to add any needed common mode shift. This arbitrary signal is then passed through a current
limiting resistor before reaching the DUT. To change the current range of the system, different current limiting
resistors are added in series with each channel of the multiplexer. In this example, the first channel of the
multiplexer uses a 10 kΩ resistor for the low current clamp. The maximum output current of the PMU in this
range is 5 mA because of this design. During the system operation, the PMU is set to this lower current range
in the beginning of the test routine. After the DUT is initially checked in this range and is operating normally with
no unexpected shorts, the current range can be switched to high current. This way the PMU and DUT will not
be unnecessarily damaged from excess current due to a short. In this example, the remaining three channels of
the TMUX8212 are connected in parallel, increasing the maximum current through the device and reducing the
low On-Resistance. Because of the flexibility of the TMUX8212, this could easily be modified to fit any system
need. For example, if less maximum current is needed, then two channels could be connected in parallel instead
of three, and the additional single channel could be used to add a third current range option. The additional input
channels make this multiplexed application increasingly valuable by greatly reducing solution size.
The TMUX821x switches have exceptionally flat On-Resistance and low leakage currents across the signal
voltage range. The ultra-flat On-Resistance keeps the current clamp constant across the signal voltage range,
and the low leakage current reduces the potential noise/offset when measuring on the lowest current range.
Additionally, excellent crosstalk and off-isolation performance allows the TMUX821x devices to perform well in
multi-channel switching applications without having an unselected channel impact the measurement on selected
channels.

TMUX821x devices. Figure 10-2 shows the leakage current for a channel that is ON across a varying source
voltage. Figure 10-3 shows the extremely flat On-Resistance across source voltage while operating within the
flattest RON range of the TMUX821x devices. These features make the devices an ideal solution for applications
that require excellent linearity and low distortion.

11 Power Supply Recommendations
The TMUX821x devices operate across a wide supply range of ±10 V to ±50 V (10 V to 100 V in single-supply
mode). They also perform well with asymmetrical supplies such as VDD = 50 V and VSS= –10 V. For improved
supply noise immunity, use a supply decoupling capacitor ranging from 1 µF to 10 µF at both the VDD and VSS
pins to ground. An additional 0.1 µF capacitor placed closest to the supply pins will provide the best supply
decoupling solution. Always ensure the ground (GND) connection is established before supplies are ramped.

12 Layout
12.1 Layout Guidelines
The image below illustrates an example of a PCB layout with the TMUX821x device. Some key considerations
are:
•
•
•
•
For reliable operation, connect at least one decoupling capacitor ranging from 0.1 µF to 10 µF between VDD
and VSS to GND. We recommend a 0.1 µF and 1 µF capacitor, placing the lowest value capacitor as close to
the pin as possible. Make sure that the capacitor voltage rating is sufficient for the supply voltage.
Keep the input lines as short as possible.
Use a solid ground plane to help distribute heat and 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.
