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

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACTcircuits outside databook specifications.
