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-type 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 Clock and Master Reset are common to all storage elements. Ordering Information Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number. All packages are lead free per JEDEC: J-STD-020B standard.
