3 Description

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. The

devices work with a single supply (4.5 V to 44 V), dual

supplies (±4.5 V to ±22 V), or asymmetric supplies

supports bidirectional analog and digital signals on the

The switches of the TMUX721x are controlled with

appropriate logic control inputs on the SELx pins. The

TMUX721x are part of the precision switches and

multiplexers family of devices and have very low on

and off leakage currents allowing them to be used in

high precision measurement applications.

The TMUX721x family provides latch-up immunity,

preventing undesirable high current events between

parasitic structures within the device typically caused

by overvoltage events. 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 the TMUX721x family of switches and

multiplexers to be used in harsh environments.
