Octal D Flip-Flop
General Description
The ’F273 has eight edge-triggered D-type flip-flops with in-
dividual D inputs and Q outputs. The common buffered
Clock (CP) and Master Reset (MR) inputs 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.
