3 Description

The TMUX7411F, TMUX7412F, and TMUX7413F

are

complementary

metal-oxide

semiconductor

(CMOS) analog switches in 1:1 (SPST), 4-channel

configurations. The devices work well with dual

supplies (±5 V to ±22 V), a single supply (8 V to

in powered and powered-off conditions, making

the TMUX741xF devices suitable for applications

where power supply sequencing cannot be precisely

controlled.

The devices block fault voltages up to +60 V or

−60 V relative to ground in powered and powered-off

conditions. When no power supplies are present the

switch channels remain in the OFF state regardless of

switch input conditions, and any control signal present

on the logic pins is ignored. If the signal path input

voltage on any Sx pin exceeds the supply voltage

turns OFF and the Sx pin becomes high impedance.

The drain pin (Dx) of a selected channel under a fault

condition is floating. The TMUX741xF devices provide

an active-low interrupt flag (FF) to indicate if any of

the source inputs are experiencing a fault condition to

help system diagnostics.
