The ACTQ273 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 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.

The ACTQ utilizes Fairchild Quiet technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet features
output control and undershoot corrector in addition to a split ground bus for superior performance.
s ICC reduced by 50% s Guaranteed simultaneous switching noise level and
dynamic threshold performance s Guaranteed pin-to-pin skew AC performance s Improved latch-up immunity s Buffered common clock and asynchronous master reset s Outputs source/sink 24 mA s 4 kV minimum ESD immunity
