The 74FCT273A is octal D flip-flops built using an advanced dual metal CMOS technology. The IDT54/ 74FCT273/A/C have eight edge-triggered D-type flip-flops with individual D inputs and O outputs. The common buffered Clock (CP) and Master Reset (MR ) inputs load and reset (clear) all flip-flops simultaneously.

The register of the 74FCT273A is fully edge-triggered. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding flip-flop's O output.

All outputs of the 74FCT273A 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.
