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: t_pd(D to Q) = 12 ns typ (C_L= 50 pF)

High Output Current: Fanout of 10 LSTTL Loads

Wide Operating Voltage: V_CC= 2 to 6 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I_CC(static) = 2 µA max (Ta = 25°C)
