1 Introduction
The TMUX7211EVM, TMUX7212EVM, and TMUX7213EVM support evaluation of the TMUX7211, TMUX7212,
and TMUX7213 devices in the 16-pin TSSOP (PW) package respectively. The TMUX7211, TMUX7212, and
TMUX7213 are complementary metal-oxide semiconductor (CMOS) switches with four independently selectable
1:1, single-pole single-throw (SPST) switch channels. These device support 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). TMUX7211,
TMUX7212, and TMUX7213 support bidirectional analog and digital signals on the source (Sx) and drain (Dx)
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
allows voltages on the control pins to be applied before the supply pin, protecting the devices from potential
damage.

2 Information About Cautions and Warnings
CAUTION
This EVM contains components that can potentially be damaged by electrostatic discharge. Always
transport and store the EVM in its supplied ESD bag when not in use. Handle using an antistatic
wristband. Operate on an antistatic work surface. For more information on proper handling, see
Electrostatic Discharge (ESD) application report
.
3 Features of this EVM
The EVM has the following features:
• 35 tests points (including 7 GND test points), which allows easy access for measuring signals
• Quick prototyping and testing setup for the TMUX7211, TMUX7212, and TMUX7213 devices in the 16-pin
TSSOP (PW) package
• No specific TMUX721x device is supplied or soldered to the evaluation modules, which allows flexibility to
choose the desired IC for evaluation
• Support for both single supply and dual supply operation
• Six power supply decoupling capacitors (2 × 0.1 μF, 2 × 1 μF, and 2 × 10 μF)
• Jumpers to eight signal lanes, VDD and VSS power rails, and control signals
• Eight pads are available for placement of SMA connectors
• Pads are available for pull-up or pull-down resistors on control signal pathways
• Pads are available for surge protection diodes
• 0805 capacitor pads are available on all signal pathways referenced to ground
