74AHC374; 74AHCT374

Octal D-type flip-flop; positive edge-trigger; 3-state

The 74AHC374; 74AHCT374 is an octal positive-edge triggered D-type flip-flop with 3-state outputs. The device features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. 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 flip-flops. Inputs are overvoltage tolerant. The 74AHCT374 device features TTL compatible inputs that are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

特性

  • Balanced propagation delays

  • All inputs have Schmitt-trigger actions

  • Wide supply voltage range from 2.0 V to 5.5 V

  • Overvoltage tolerant inputs to 5.5 V

  • High noise immunity

  • CMOS low power dissipation

  • Common 3-state output enable input

  • Input levels:

    • For 74AHC374: CMOS level

    • For 74AHCT374: 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

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