The M74HC14 is a high speed CMOS hex Schmitt inverter fabricated with silicon gate C2MOS technology. Pin configuration and functions are the same as those of the M74HC04 but all inputs have a 20 % VCC hysteresis level. This, together with the Schmitt trigger function, allows the device 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.
High speed: tPD = 12 ns (typ.) at VCC = 6 V
Low power dissipation: ICC = 1 μA (max.) at TA = 25 °C
High noise immunity: VH = 1.2 V (typ.) at VCC = 6 V
Symmetrical output impedance: |IOH| = IOL = 4 mA (min.)
Balanced propagation delays: tPLH ≃ tPHL
Wide operating voltage range: VCC (opr) = 2 to 6 V
Pin and function compatible with 74 series 14
