It is ideal for low power applications mantaining high speed operation similar to B M (Plastic Package) (Micro Package) ORDER CODES : 74AC14B 74AC14M equivalent Bipolar Shottky TTL. The internal circuit is composed of 3 stages including buffer output, which enables high noise immunity and stable output. This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input segnals. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
