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.
