Octal D-Type Flip-Flop with Clock Enable

General Description

The AC/ACT377 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.

The register is fully edge-triggered. The state of each D

input, 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.

Ordering Code:

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
