3 Description

The TMUX1111, TMUX1112, and TMUX1113 are

precision complementary metal-oxide semiconductor

(CMOS) devices that have four independently

selectable 1:1, single-pole, single-throw (SPST)

switches. Wide operating supply of 1.08V to 5.5V

allows for use in a broad array of applications from

medical equipment to industrial systems. The device

supports bidirectional analog and digital signals on the

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

VDD.

The switches of the TMUX1111 are turned on with

Logic 0 on the appropriate logic control inputs,

while Logic 1 is required to turn on switches in

the TMUX1112. The four channels of the TMUX1113

are split with two switches supporting Logic 0,

while the other two switches support Logic 1. The

TMUX1113 exhibits break-before-make switching,

allowing the device to be used in cross-point switching

applications.

The TMUX111x devices are part of the precision

switches and multiplexers family. These devices have

very low on and off leakage currents and low charge

injection, allowing them to be used in high precision

measurement applications. A low supply current of 8

nA and small package options enable use in portable

applications.
