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.

• Ideal for Addressable Register Applications

• Clock Enable for Address and Data Synchronization Applications

• Eight Edge-Triggered D Flip-Flops

• Buffered Common Clock

• Outputs Source/Sink 24 mA
