FEATURES
High impedance inputs for reduced loading
(20
μ
A in Low and High states)
Ideal buffer for MOS microprocessor or memory
Eight edge–triggered D–type flip–flops
Buffered common clock
Buffered asynchronous Master Reset
See 74F377A for clock enable version
See 74F373 for transparent latch version
See 74F374 for 3–State version
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.
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.
