TMUX582FPWTSEP [Texas Instruments]

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 on-resistance. 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.
