74ABT273 datasheet



The 74ABT273 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 MRinput. 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.
