MC74ACT377
Octal D FlipĆFlop
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.
Ideal for Addressable Register Applications
Clock Enable for Address and Data Synchronization Applications
