74VHC14 - HEX SCHMITT INVERTER

General Description

The 74VHC14 device is an advanced high-speed CMOS hex Schmitt inverter manufactured with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

The internal circuit is composed of 3 stages including a buffer output, which provides high noise immunity and stable output.

Key Features

  • High speed: tPD = 5.5 ns (typ. ) at VCC = 5 V.
  • Low power dissipation.
  • ICC = 2 μA (max. ) at TA = 25 °C.
  • Typical hysteresis: Vh = 1 V at VCC = 4.5 V.
  • Power-down protection on inputs.
  • Symmetrical output impedance |IOH| = IOL = 8 mA (min. ).
  • Balanced propagation delay: tPLH ≅ tPHL.
  • Operating voltage range.
  • VCC (opr. ) = 2 V to 5.5 V.
  • Pin and function compatible with 74 series 14.
  • Improved latch-up immunity.
  • Low noise.
  • VOL.
