General Description
54FCT273PCQR General Description
The 'FCT273 has eight edge-triggered D-type flip-flops with individual D inputs and Q outputs The common buffered Clock (CP) and Master Reset (MR) input load and reset (clear) all flip-flops simultaneously
The register is fully edge-triggered The state of each D in-put one setup time before the LOW-to-HIGH clock tran-sition is transferred to the corresponding flip-flop's Q out-put 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
