54ACTQ377  
Octal D Flip-Flop with Clock Enable  
General Description  
Features  
n Ideal for addressable register applications  
n Clock enable for address and data synchronization  
applications  
The ACTQ377 has eight edge-triggered, D-type flip-flops  
with individual D inputs and Q outputs. The common buff-  
ered Clock (CP) input loads all flip-flops simultaneously,  
when the Clock Enable (CE) is LOW.  
n Eight edge-triggered D flip-flops  
n Buffered common clock  
n Outputs source/sink 24 mA  
n See ’273 for master reset version  
n See ’373 for transparent latch version  
n See ’374 for TRI-STATE® version  
n Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
The register is fully edge-triggered. The state of each D in-  
put, one setup time before the LOW-to-HIGH clock transi-  
tion, 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.  
The ACTQ377 utilizes FACT Quiet Series® technology to  
guarantee quiet output switching and improved dynamic  
threshold performance. FACT Quiet Series features GTO®  
output control and undershoot corrector in addition to a split  
ground bus for superior performance.
