    74HCT573PW

    Octal D-type transparent latch; 3-state

    The 74HC573; 74HCT573 is an 8-bit D-type transparent latch with 3-state outputs. The device features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs enter the latches. In this condition the latches are transparent, a latch output will change each time its corresponding D-input changes. When LE is LOW the latches store the information that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the latches. Inputs include clamp diodes. This enables 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 to 6.0 V
    • CMOS low power dissipation
    • High noise immunity

    • Input levels:

      • For 74HC573: CMOS level

      • For 74HCT573: TTL level

    • Inputs and outputs on opposite sides of package allowing easy interface with microprocessors

    • Useful as input or output port for microprocessors and microcomputers

    • 3-state non-inverting outputs for bus-oriented applications

    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.
