3 Description

The TMUX541x is a general purpose complementary

metal-oxide semiconductor (CMOS) switch device

with four independently selectable 1:1, single-pole,

single-throw (SPST) switch channels. The device

works with a single supply (4.5V to 50V), dual

supplies (±4.5V to ±25V), or asymmetric supplies

(such as VDD = 37.5V, VSS = –12.5V). The TMUX541x

supports bidirectional analog and digital signals on the

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

VDD.

The switches of the TMUX541x are controlled with

appropriate logic control inputs on the SELx pins. The

TMUX541x exhibits break-before-make switching,

allowing the device to be used in cross-point and

multiplexing applications.

The TMUX541x is a part of the general purpose

switches and multiplexers family of devices

emphasizing uses in broad range of applications while

reducing BOM cost.
