74AHC257PW

Quad 2-input multiplexer; 3-state

The 74AHC257; 74AHCT257 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.

Features and benefits

  • Balanced propagation delays

  • All inputs have Schmitt-trigger actions

  • Non-inverting data path

  • Wide supply voltage range from 2.0 V to 5.5 V

  • Input levels:

    • For 74AHC257: CMOS level

    • For 74AHCT257: TTL level

  • Overvoltage tolerant inputs to 5.5 V

  • 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

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

Sample

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
