HD74HC77

4-bit Bistable Latch

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.

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)
