Octal D FlipFlop 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.
