Pin configuration and function are the same as those of the M74HCT04 but all inputs have 0.7 V hysteresis level. This together with its schmitt trigger function allows it to be used on line receiver with slow rise/fall input signals. The M74HCT14 is designed to directly interface HSC2MOS systems with TTL and NMOS components. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
