It has the same high speed performance of LSTTL combined with true CMOS low power consumption. Pin configuration and function are the same as those of the HC04 but all inputs have 20 % VCC hysteresis level. This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
