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 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
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
