3 Description

The TMUX582F-SEP is a modern 8:1 multiplexer

suitable for single ended operation. This latch-up

immune device offers robust overvoltage protection

up to +60V making it optimal for harsh space

environments. Additionally, this protection operates

in powered-on, powered-off, and floating supply

conditions.

During a fault such as an overvoltage or undervoltage

event, the offending channel turns OFF and the Sx

pin becomes high impedance. If this fault channel is

selected, the drain (D) is pulled to the fault rail that

is exceeded (Vfp or Vfn). All other Sx pins which

are not under fault continue to operate normally.

During normal operation, when the source (Sx) does

not exceed Vfp or Vfn, the switch operates with

low leakage, low capacitance and an ultra-flat onresistance.

This provides high performance signal

integrity with minimal distortion.

The TMUX582F-SEP is a fault protected CMOS

multiplexer flexible enough to handle almost any

application, from system monitoring, to power-up

sequencing protection, to high precision front end

data acquisition.
