DESCRIPTION

The 74F377A has 8 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 Enable (E) input is Low.

The register is fully edge triggered. The state of each D input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop’s Q output.

The E input must be stable one setup time prior to the Low-to-High clock transition for predictable operation.

FEATURES

? High impedance inputs for reduced loading (20μA in Low and High states)

? Ideal for addressable register applications

? Enable for address and data synchronization applications

? Eight edge–triggered D–type flip–flops

? Buffered common clock

? See ’F273A for Master Reset version
