74HC74BZ

Dual D-type flip-flop with set and reset; positive edge-trigger

The 74HC74 and 74HCT74 are dual positive edge triggered D-type flip-flop. They have individual data (nD), clock (nCP), set (nSD) and reset (nRD) inputs, and complementary nQ and nQ outputs. Data at the nD-input, that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition, is stored in the flip-flop and appears at the nQ output. Schmitt-trigger action in the clock input, makes the circuit highly tolerant to slower clock rise and fall times. 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 to 6.0 V
  • CMOS low power dissipation
  • High noise immunity
  • Input levels:

    • For 74HC74: CMOS level

    • For 74HCT74: TTL level

  • Symmetrical output impedance

  • High noise immunity

  • Balanced propagation delays

  • 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

  • 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.
