DESCRIPTION
The 74ABT273A 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.
All outputs will be forced Low independent 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 elements.
