Octal D Flip-Flop
General Description
The ’273 has eight edge-triggered D-type flip-flops with indi-
vidual D inputs and Q outputs The common buffered Clock
(CP) and Master Reset (MR) input load and reset (clear) all
flip-flops simultaneously
The register is fully edge-triggered The state of each D in-
put one setup time before the LOW-to-HIGH clock tran-
sition is transferred to the corresponding flip-flop’s Q out-
put
All outputs will be forced LOW independently of Clock or
Data inputs by a LOW voltage level on the MR input The
device is useful for applications where the true output only is
required and the Clock and Master Reset are common to all
storage elements
