3 Description

The TMUX6211, TMUX6212, and TMUX6213 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 (4.5V to 36V),

dual supplies (±4.5V to ±18V), or asymmetric supplies

(such as VDD = 12V, VSS = –5V). The TMUX621x

supports bidirectional analog and digital signals on the

source (Sx) and drain (Dx) pins ranging from VSS to

VDD.

The switches of the TMUX621x are controlled with

appropriate logic control inputs on the SELx pins. The

TMUX621x 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.
