LM2903B-Q1: About EDS protection

user6345333
Prodigy 210 points
Part Number: LM2903B-Q1

Tool/software:

To the person in charge

I assume there is an ESD protection element connected to each terminal,
After the ESD protection element is turned on when a surge voltage is applied, at what voltage does it release the trigger?
Since the rated voltage is 36V, I thought the trigger would be released at 36V, is this correct?

Best regards

Shingu

    Inputs yes. The outputs are are self protecting.

    Sorry, I don't have data for this.

    That is not necessarily true. 

    Adding resistance to input path, helps protect input and not having sufficient hold current. I wouldn't expect output to latch. Try to avoid ESD events as much as possible.
