MC74AC377, MC74ACT377  
Octal D Flip−Flop with  
Clock Enable  
The MC74AC377/74ACT377 has eight edge-triggered, D-type  
flip-flops with individual D inputs and Q outputs. The common  
buffered Clock (CP) input loads all flip-flops simultaneously, when  
the Clock Enable (CE) is LOW. The register is fully edge-triggered.  
The state of each D input, one setup time before the LOW-to-HIGH  
clock transition, is transferred to the corresponding flip-flop’s Q  
output. The CE input must be stable only one setup time prior to the  
LOW-to-HIGH clock transition for predictable operation.
