74HC14D

 The 74HC14D is a high speed CMOS SCHMITT INVERTER fabricated with silicon gate C 2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Pin configuration and function are the same as the 74HC04D but the inputs have 25% VCC hysteresis and with its schmitt trigger function, the 74HC14D can be used as a line receivers which will receive slow input signals.

 All inputs are equipped with protection circuits against static discharge or transient excess voltage.
