74AHC126; 74AHCT126

Quad buffer/line driver; 3-state

The 74AHC126; 74AHCT126 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A LOW on nOE causes the outputs to assume a high-impedance OFF-state. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

特性

  • Balanced propagation delays

  • All inputs have Schmitt-trigger action

  • Inputs accept voltages higher than VCC

  • Input levels:

    • For 74AHC126: CMOS level

    • For 74AHCT126: 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
