The 74HC14D is a high speed CMOS SCHMITT INVERTER fabricated with silicon gate C2MOS 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 receiver which will receive slow input signals. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features

High speed: tpd = 11 ns (typ.) at VCC = 5 V
Low power dissipation: ICC = 1.0µA (max) at Ta = 25
High noise immunity: VH = 1.1 V (typ.) at VCC = 4.5 V
Balanced propagation delays: tPLH≈ tPHL
Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V
