54FCT273 August 1998 54FCT273 Octal Octal D-Type Flip-Flop General Description Features D-T The FCT273 has eight edge-triggered D-type flip-flops with n Eight edge-triggered D flip-flops individual D inputs and Q outputs. The common buffered ype n Buffered common clock Clock (CP) and Master Reset (MR) inputs load and reset n Buffered, asynchronous Master Reset (clear) all flip-flops simultaneously. n See FCT377 for clock enable version Flip-Flop The register is fully edge-triggered. The state of each D in- n See FCT373 for transparent latch version put, one setup time before the LOW-to-HIGH clock transi- n See FCT374 for TRI-STATE® version tion, is transferred to the corresponding flip-flop s Q output. n Output sink capability of 32 mA, source capability of All outputs will be forced LOW independently of Clock or 12 mA Data inputs by a LOW voltage level on the MR input. The de- n TTL input and output level compatible vice is useful for applications where the true output only is re- n CMOS power consumption quired and the Clock and Master Reset are common to all n Standard Microcircuit Drawing (SMD) 5962-8765601 storage elements.
