8.3.6.3 TMUX13xxA-Q1 is Unpowered and the Input Signal has a Voltage Present (VDD = 0V, VINPUT = 3V)

Many CMOS switches are unable to support a voltage at the input without a valid supply voltage present, otherwise the voltage will be coupled from input to output and could damage downstream devices or impact power-sequencing. The TMUX13xxA-Q1 circuitry can handle an input signal present without a supply voltage while minimizing power transfer from the input to output of the switch. By limiting the output voltage coupling to 400mV the TMUX1308A-Q1 and TMUX1309A-Q1 help reduce the chance of conduction through any downstream ESD diodes.
