breaks down. In the case where an overvoltage is impressed between signal pins, the protection path is through a

diode from the first pin to V+, through the diode stack, and through a diode from V– to the second pin.

The electrical overstress protection is meant primarily for electrostatic discharge (ESD) protection. Secondarily, it is

able to handle some amount of signal overdrive, provided adequate current limitation is provided to ensure less

than +10 mA flows into the pin, as noted in Absolute Maximum Ratings.
