Octal D-Type Flip-Flop with Clock Enable

General Description

Features

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.

■ I_CCreduced by 50%

■ Ideal for addressable register applications

■ Clock enable for address and data synchronization

applications

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.

■ Eight edge-triggered D-type flip-flops

■ Buffered common clock

■ Outputs source/sink 24 mA

■ See 273 for master reset version

■ See 373 for transparent latch version

■ See 374 for 3-STATE version

■ ACT377 has TTL-compatible inputs
