Power Supply sequencing requirements for ADG451, ADG452, ADG453

Q

What are the Power Supply sequencing requirements for ADG452?

A

You should not power up VL before VDD or you will be exceeding the
absolute max ratings for the part (VL to GND = −0.3 V to VDD + 0.3 V) and will
result in part failure, if this occurs often it will lead to part failure,
using external shottky diodes and a series limiting resistor will protect the
part from latch up should this occur.
