Hex Schmitt Inverter

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.

Key Features

  • 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
  • ESD performance
    • CDM: 1 kV
    • HBM: 2 kV
    • MM: 200 V
