74ABT273A
Octal D-type flip-flop
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.
