Overview
54ABT377 Octal D-Type Flip-Flop with Clock Enable July 1998 54ABT377 Octal D-Type Flip-Flop with Clock Enable General Description The ’ABT377 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 n Clock enable for address and data synchronization applications n Eight edge-triggered D flip-flops n Buffered common clock n See ’ABT273 for master reset version n See ’ABT373 for transparent latch version n See ’ABT374 for TRI-STATE® version n Output sink capability of 48 mA, source capability of 24 mA n Guaranteed latchup protection n High...
