    74AHC273D

    Octal D-type flip-flop with reset; positive-edge trigger

    The 74AHC273; 74AHCT273 is an octal positive-edge triggered D-type flip-flop. The device features clock (CP) and master reset (MR) inputs. The outputs Qn will assume the state of their corresponding D inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A LOW on MR forces the outputs LOW independently of clock and data inputs. 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 to 5.5 V

    • Overvoltage tolerant inputs to 5.5 V

    • High noise immunity

    • CMOS low power dissipation

    • Balanced propagation delays

    • All inputs have Schmitt-trigger actions

    • Ideal buffer for MOS microcontroller or memory

    • Common clock and master reset

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

    • Input levels:

      • For 74AHC273: CMOS level

      • For 74AHCT273: 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

    • 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.
