Power sequencing indicates that the power voltages in a multi-power system are not ramping up at the same time, therefore signals from difference power source applied to a device while its Vcc is not reaching nominal voltage yet and causing problem.

Power sequencing indicates that the voltage at the Vcc pin is 0V while the input signals are applied to the in/out pins of the switch. It is a similar condition to hot-swap. Therefore the switches that work for hot-swap applications also apply to power sequencing.
