3 Description

The TMUX8211, TMUX8212, and TMUX8213 are

modern high voltage capable analog switches

with Latch-Up immunity. Each device has four

independently controllable 1:1, single-pole singlethrow

(SPST) switch channels. The devices work well

with dual supplies, a single supply, or asymmetric

supplies up to a maximum supply voltage of 100 V.

The TMUX821x devices provide consistent analog

parametric performance across the entire supply

voltage range. The TMUX821x family supports

bidirectional analog and digital signals on the source

(Sx) and drain (Dx) pins.

All logic inputs support logic levels of 1.8 V, 3.3 V, and

5 V and can be connected as high as 48 V, allowing

for system flexibility with control signal voltage. Failsafe

logic circuitry allows voltages on the logic pins to

be applied before the supply pin, protecting the device

from potential damage.

The device family provides Latch-Up immunity,

preventing undesirable high current events between

parasitic structures within the device. 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 this family of

multiplexers to be used in harsh environments.
