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

44 V), or asymmetric supplies (such as VDD = 12 V,

VSS = –5 V). The overvoltage protection is available

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 the 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 (VDD or VSS) by a threshold voltage (VT), the

channel 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.
