TMUX7208EVM Evaluation Module 1
Copyright © 2020 Texas Instruments Incorporated

1 Introduction
The TMUX7208EVM supports evaluation of the TMUX7208 device in the 16-pin TSSOP (PW) package.
TMUX7208 is a complementary metal-oxide semiconductor (CMOS) switch with latch-up immunity in a 8:1 single
channel configuration. The device supports dual supplies (±4.5 V to ±22 V), a single supply (4.5 V to 44 V), or
asymmetric supplies (such as VDD = 12 V, VSS = –5 V). The TMUX7208 supports bidirectional analog and
digital signals on the source (Sx) and drain (D) pins ranging from VSS to VDD. All logic control inputs support
logic levels from 1.8 V to VDD, ensuring both TTL and CMOS logic compatibility when operating in the valid
supply voltage range. The Fail-Safe Logic circuitry applies voltages on the control pins before the supply pin,
which protects the device from potential damage.

4.1 EVMS ARE NOT FOR USE IN FUNCTIONAL SAFETY AND/OR SAFETY CRITICAL EVALUATIONS, INCLUDING BUT NOT
LIMITED TO EVALUATIONS OF LIFE SUPPORT APPLICATIONS.
4.2 User must read and apply the user guide and other available documentation provided by TI regarding the EVM prior to handling
or using the EVM, including without limitation any warning or restriction notices. The notices contain important safety information
related to, for example, temperatures and voltages.
4.3 Safety-Related Warnings and Restrictions:
4.3.1 User shall operate the EVM within TI’s recommended specifications and environmental considerations stated in the user
guide, other available documentation provided by TI, and any other applicable requirements and employ reasonable and
customary safeguards. Exceeding the specified performance ratings and specifications (including but not limited to input
and output voltage, current, power, and environmental ranges) for the EVM may cause personal injury or death, or
property damage. If there are questions concerning performance ratings and specifications, User should contact a TI
field representative prior to connecting interface electronics including input power and intended loads. Any loads applied
outside of the specified output range may also result in unintended and/or inaccurate operation and/or possible
permanent damage to the EVM and/or interface electronics. Please consult the EVM user guide prior to connecting any
load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative.
During normal operation, even with the inputs and outputs kept within the specified allowable ranges, some circuit
components may have elevated case temperatures. These components include but are not limited to linear regulators,
switching transistors, pass transistors, current sense resistors, and heat sinks, which can be identified using the
information in the associated documentation. When working with the EVM, please be aware that the EVM may become
very warm.
