Description

The 74ACTQ273 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 Dtype input, one setup time before the LOW-to-HIGH clock transition, is transferred to the corresponding flip-flop's Qoutput.
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.
The ACTQ utilizes Fairchild Quiet Series technology of the 74ACTQ273 to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features
GTO output control and undershoot corrector in addition to a split ground bus for superior performance.
