74VHC14; 74VHCT14

Hex inverting Schmitt trigger

The 74VHC14; 74VHCT14 are high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A.

The 74VHC14; 74VHCT14 provide six inverting buffers with Schmitt-trigger action. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.

特性

  • Balanced propagation delays

  • All inputs have Schmitt-trigger action

  • Inputs accept voltages higher than VCC

  • Input levels:

    • The 74VHC14 operates with CMOS input level

    • The 74VHCT14 operates with TTL input level

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Multiple package options

  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
