3 Description

The TMUXS7614D is a complementary metal-oxide

semiconductor (CMOS) switch device with eight

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

(SPST) switch channels. The device works with a

single supply (4.5V to 42V), dual supplies (±4.5V

to ±25V), or asymmetric supplies (such as VDD =

37.5V, VSS = –12V). The TMUXS7614D supports

bidirectional analog and digital signals on the source

(Sx) and drain (Dx) pins ranging from VSS to VDD.

The switches of the TMUXS7614D are controlled with

a serial peripheral interface (SPI). The SPI interface

has many error detection features, such as CRC,

invalid read/write, and clock count error detection.

The SPI also supports Daisy Chain mode. Coupled

with the flow through routing of the SPI pins, this

allows for increased channel density in the system.

The TMUXS7614D is a part of the precision switches

and multiplexers family of devices that have very low

on and off leakage currents allowing them to be used

in high precision measurement applications.
