3 Description
The TMUX6211, TMUX6212, and TMUX6213 are
complementary metal-oxide semiconductor (CMOS)
switches with four independently selectable 1:1,
single-pole, single-throw (SPST) switch channels. The
devices work with a single supply (4.5V to 36V),
dual supplies (±4.5V to ±18V), or asymmetric supplies
(such as VDD = 12V, VSS = –5V). The TMUX621x
supports bidirectional analog and digital signals on the
source (Sx) and drain (Dx) pins ranging from VSS to
VDD.
The switches of the TMUX621x are controlled with
appropriate logic control inputs on the SELx pins. The
TMUX621x are part of the precision switches and
multiplexers family of devices and have very low on
and off leakage currents allowing them to be used in
high precision measurement applications.
