54AC273 Octal D Flip-Flop

The ’273 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 D input, one setup time before the LOW-.
