74AC377, 74ACT377 Octal D-Type Flip-Flop with Clock Enable Features General Description ■ ICC reduced by 50% The AC/ACT377 has eight edge-triggered, D-type flipflops 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. ■ Ideal for addressable register applications ■ Clock enable for address and data synchronization ■ ■ ■ ■ ■ ■ ■ applications Eight edge-triggered D-type flip-flops Buffered common clock Outputs source/sink 24mA See 273 for master reset version See 373 for transparent latch version See 374 for 3-STATE version ACT377 has TTL-compatible inputs 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.
