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)
