54F 74F377
Octal D Flip-Flop with Clock Enable
General Description
The ’F377 has eight edge-triggered D-type flip-flops 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
The register is fully edge-triggered The state of each D in-
put one setup time before the LOW-to-HIGH clock tran-
sition is transferred to the corresponding flip-flop’s Q out-
put The CE input must be stable only one setup time prior
to the LOW-to-HIGH clock transition for predictable opera-
tion
Features
Y Ideal for addressable register applications
Y Clock enable for address and data synchronization
applications
Y Eight edge-triggered D flip-flops
Y Buffered common clock
Y See ’F273 for master reset version
Y See ’F373 for transparent latch version
Y See ’F374 for TRI-STATE version
Y Guaranteed 4000V minimum ESD protection
