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.
