74HC377; 74HCT377

Octal D-type flip-flop with data enable; positive-edge trigger

The 74HC377; 74HCT377 is an octal positive-edge triggered D-type flip-flop. The device features clock (CP) and data enable (E) inputs. When E is LOW, the outputs Qn assume the state of their corresponding Dn inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. Input E must be stable one set-up time prior to the LOW-to-HIGH transition for predictable operation. 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 V to 6.0 V

  • 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)
  • Common clock and master reset

  • Eight positive edge-triggered D-type flip-flops

  • Input levels:

    • For 74HC377: CMOS level

    • For 74HCT377: TTL level

  • ESD protection:

    • HBM JESD22-A114F exceeds 2 kV

    • MM JESD22-A115-A exceeds 200 V

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