3 Description

The TMUX7212 is a complementary metaloxide

semiconductor (CMOS) switch with four

independently selectable 1:1, single-pole, single-throw

(SPST) switch channels. This device works with a

single supply (4.5V to 44V), dual supplies (±4.5V to

±22V), or asymmetric supplies (such as VDD = 12V,

VSS = –5V). The TMUX721x supports bidirectional

analog and digital signals on the source (Sx) and

drain (Dx) pins ranging from VSS to VDD.

The switches of the TMUX721x are controlled with

appropriate logic control inputs on the SELx pins.

The TMUX721x is part of the precision switches and

multiplexers family of devices and has very low on

and off leakage currents allowing them to be used in

high precision measurement applications.

The TMUX721x 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 to be used in harsh

environments.
