General Description
The ’273has eight edge-triggered D-type flip-flopswith indi-
vidualD inputsandQ outputs. The common buffered Clock
(CP)and Master Reset (MR) input loadand reset (clear)all
flip-flops simultaneously.
The registeris fully edge-triggered.The stateof eachDin-
put, one setup time beforethe LOW-to-HIGH clock tran-
sition,is transferredtothe corresponding flip-flop’sQout-
put.
All outputswillbe forced LOW independentlyof Clockor
Data inputsbya LOW voltage levelontheMR input.The
deviceis usefulforapplications wherethe trueoutput onlyis
requiredandthe Clockand Master Resetarecommontoall
storage elements.
