    74HCT251PW

    8-input multiplexer; 3-state

    The 74HC251; 74HCT251 is an 8-bit multiplexer with eight binary inputs (I0 to I7), three select inputs (S0 to S2) and an output enable input (OE). The select inputs select one of the eight binary inputs and route it to the complementary outputs (Y and Y). A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.

    Features and benefits

    • Wide supply voltage range from 2.0 V to 6.0 V

    • CMOS low power dissipation

    • High noise immunity

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

    • Complies with JEDEC standards:

      • JESD8C (2.7 V to 3.6 V)
      • JESD7A (2.0 V to 6.0 V)

    • Input levels:

      • For 74HC251: CMOS level

      • For 74HCT251: TTL level

    • Non-inverting data path

    • 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

    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.
