FEATURES
DESCRIPTION
The 74F273 has eight edge–triggered D–type flip–flops with
individual 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 input, one
setup time before the Low–to–High clock transition, is transferred to
the corresponding flip–flop’s Q output.

DESCRIPTION

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 CP and
MR are common to all elements.
