Description
PericomSemiconductor’s PI74FCT273Tisa8-bitwideoctaldesigned
with eight edge-triggered D-type flip-flops with individual D inputs
and O outputs. The common buffered Clock (CP) and Master Reset
(MR) load and resets (clear) all flip-flops simultaneously. The
register is fully edge-triggered. The D input state, one setup time
before the LOW-to-HIGH clock transition, is transferred to the
corresponding flip-flop's O output. All outputs will be forced LOW
independently of Clock or Data inputs by a LOW voltage level on
the MR input.
Device models available upon request.
