    74HCT280D

    9-bit odd/even parity generator/checker

    The 74HC280; 74HCT280 is a 9-bit parity generator or checker. Both even and odd parity outputs are available. The even parity output (PE) is HIGH when an even number of data inputs (I0 to I8) is HIGH. The odd parity output (PO) is HIGH when an odd number of data inputs are HIGH. Expansion to larger word sizes is accomplished by tying the even outputs (PE) of up to nine parallel devices to the final stage data inputs. Inputs include clamp diodes. It enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

    Features and benefits

    • Word-length easily expanded by cascading

    • Generates either odd or even parity for nine data bits

    • Wide supply voltage range from 2.0 to 6.0 V

    • Input levels:

      • For 74HC280: CMOS level

      • For 74HCT280: TTL level

    • 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)

    • 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 -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.
