Honored ContributorMax 2 IC occasionally gets destroyed
In my hardware environment, a "Max 2" IC occasionally gets destroyed - it pulls down the 3.3 V power supply. What can be the cause for this? Can it be anything else than electrostatic discharge? The ...

Honored Contributor --- Quote Start --- do you connect 0V or 3.3V first when you apply the power. --- Quote End --- I think that the potentials 0 V and 3.3 V only have a meaning if there is a voltage from one to another (or to a third potential in the device). So I don't understand the question and its aim. --- Quote Start --- What kind of voltage regulator do you have on the board? --- Quote End --- It is a low-dropout regulator: ADP3338. It is on a different board. --- Quote Start --- What is the source of all the inputs to the board? --- Quote End --- At present, there are only a bus (adresses, data, control signals - from a bus transceiver IC), 5 V (from a mains adapter) and 3.3 V (from the power regulator).
