Octal D Flip-Flop with Clock Enable

n Ideal for addressable register applications

n Clock enable for address and data synchronization

applications

n Eight edge-triggered D flip-flops

n Buffered common clock

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.

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 ’ACT377 has TTL-compatible inputs

n Standard Microcircuit Drawing (SMD)

— ’AC377: 5962-88702

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.
