    74AHC244D

    Octal buffer/line driver; 3-state

    The 74AHC244; 74AHCT244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH 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.

    Features and benefits

    • Wide supply voltage range from 2.0 V to 5.5 V

    • Balanced propagation delays

    • All inputs have Schmitt-trigger action

    • Overvoltage tolerant inputs to 5.5 V

    • High noise immunity

    • CMOS low power dissipation

    • Input levels:

      • For 74AHC244: CMOS level

      • For 74AHCT244: 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

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

    • Multiple package options

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

    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.
