3 Description

The TMUX6211, TMUX6212, and TMUX6213 are

complementary metal-oxide semiconductor (CMOS)

switches with four independently selectable 1:1,

single-pole, singlethrow (SPST) switch channels. The

devices work well with dual supplies (±4.5 V to

±18 V), a single supply (4.5 V to 36 V), or asymmetric

TMUX621x supports bidirectional analog and digital

signals on the source (Sx) and drain (D) pins ranging

The switches of the TMUX6211 are turned on with

Logic 0 on the appropriate logic control inputs, while

Logic 1 is required to turn on switches in the

TMUX6212. The four channels of the TMUX6213 are

split with two switches supporting Logic 0, while the

other two switches support Logic 1. The TMUX6213

exhibits break-before-make switching, allowing the

device

to

be

used

in

cross-point

switching

applications.

The TMUX621x are part of the precision switches and

multiplexers family of devices. These devices have

very low on and off leakage currents and low charge

injection, allowing them to be used in high precision

measurement applications.
