HD74HC77 Datasheet 4-bit Bistable Latch

Manufacturer: Renesas

Overview: HD74HC77 4-bit Bistable Latch REJ03D0552-0200 (Previous ADE-205-424) Rev.2.

General Description

The HD74HC77 is ideally suited for use as temporary storage for binary information between processing units and input/output or indicator units.

Information present at a data (D) input is transferred to the Q output when the enable (G) is high and the Q output will follow the data input as long as the enable remains high.

When the enable goes low the information (that was present at the data input at the time the transition occurred) is retained at the Q output until the enable is permitted to go high.

Key Features

  • High Speed Operation: tpd (D to Q) = 12 ns typ (CL = 50 pF).
  • High Output Current: Fanout of 10 LSTTL Loads.
  • Wide Operating Voltage: VCC = 2 to 6 V.
  • Low Input Current: 1 µA max.
  • Low Quiescent Supply Current: ICC (static) = 2 µA max (Ta = 25°C).
  • Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation HD74HC77P.
