74AHC257-Q100; 74AHCT257-Q100

Quad 2-input multiplexer; 3-state

The 74AHC257-Q100 is a quad 2-input multiplexer with 3-state outputs. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.

Features and benefits

  • Automotive product qualification in accordance with AEC-Q100 (Grade 1)

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

  • Balanced propagation delays

  • All inputs have Schmitt-trigger actions

  • Non-inverting data path

  • Overvoltage tolerant inputs to 5.5 V

  • Input levels:

    • For 74AHC257-Q100: CMOS level

    • For 74AHCT257-Q100: TTL level

  • High noise immunity

  • CMOS low power dissipation

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level A

  • ESD protection:

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

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