equivalentBipolarShottky TTL. The internal circuit is composed of 3 stages

including buffer output, which enables high noise immunityand stable output.

This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fallinputsegnals.

All inputs and outputs are equipped with protectioncircuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
