Other Parts Discussed in Thread: STRIKE
Hello,
I am designing ESD protection for the LMH6643 for an event on the output pin. I would like to know the maximum allowable current into the input output pin during such an event.
The absolute maximum voltage on input/output pins is specified as a 0.8V difference (~1 diode drop) relative to the supply voltage:
The maximum recommended current through input pins during an input overvoltage is given in application notes as 10 mA:
The ESD protection circuit for the input is also shown:
Presumably the output pin is similarly protected. Should it be assumed that it is also not recommended to exceed 10 mA into the output pin during an ESD event on the device output?
Thank you.
