74AHC02; 74AHCT02

Quad 2-input NOR gate

The 74AHC02; 74AHCT02 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard No. 7-A.

The 74AHC02; 74AHCT02 provides a quad 2-input NOR function.

Features and benefits

  • Balanced propagation delays

  • All inputs have a Schmitt-trigger action

  • Inputs accept voltages higher than VCC

  • Input levels:

    • For 74AHC02: CMOS level

    • For 74AHCT02: TTL 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
