MC74AC273, MC74ACT273
Octal D FlipFlop
The MC74AC273/74ACT273 has eight edge-triggered Dtype
flipflops with individual D inputs and Q outputs. The common
buffered Clock (CP) and Master Reset (MR) inputs load and reset
(clear) all flipflops simultaneously.
The register is fully edge-triggered. The state of each D input, one
setup time before the LOWtoHIGH clock transition, is transferred
to the corresponding flipflop’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 Clock
and Master Reset are common to all storage elements.
