Latch-Up Immune
The TMUX7211, TMUX7212, and TMUX7213 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 (4.5 V to 44 V), dual
supplies (±4.5 V to ±22 V), or asymmetric supplies
(such as VDD = 12 V, VSS = –5 V). The TMUX721x
supports bidirectional analog and digital signals on the
source (Sx) and drain (Dx) pins ranging from VSS to
Dual Supply Range: ±4.5 V to ±22 V
Single Supply Range: 4.5 V to 44 V
Low On-Resistance: 2 Ω
High Current Support: 330 mA (Maximum)
(WQFN)
High Current Support: 220 mA (Maximum)
(TSSOP)
–40°C to +125°C Operating Temperature

Fail-Safe Logic
Rail-to-Rail Operation
Bidirectional Operation
The switches of the TMUX721x are controlled with
appropriate logic control inputs on the SELx pins. The
TMUX721x 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.

Sample-and-Hold Circuits
Feedback Gain Switching
Signal Isolation
The TMUX721x family provides latch-up immunity,
preventing undesirable high current events between
parasitic structures within the device typically caused
by overvoltage events. A latch-up condition typically
continues until the power supply rails are turned off
and can lead to device failure. The latch-up immunity
feature allows the TMUX721x family of switches and
multiplexers to be used in harsh environments.
