FACT DATA
The MC74AC273/74ACT273 has eight edge-triggered D-type flip-flops with
individual D inputs and Q outputs. The common buffered Clock (CP) and Master
Reset (MR
) inputs load and reset (clear) all flip-flops simultaneously.
The register is fully edge-triggered. The state of each D input, one setup time
before the LOW-to-HIGH clock transition, is transferred to the corresponding flipflop’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.
• Ideal Buffer for MOS Microprocessor or Memory
