Octal D-Type Flip-Flop with Clock Enable
Features
General Description
■ I reduced by 50%
The AC/ACT377 has eight edge-triggered, D-type flip-
flops with individual D inputs and Q outputs. The com-
mon buffered Clock (CP) input loads all flip-flops simulta-
neously, when the Clock Enable (CE) is LOW.
CC
■ 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
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.
■ 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

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
