Overview
The MC74ACT273DWR2G is an octal D-type flip-flop integrated circuit produced by onsemi. This device features eight edge-triggered D-type flip-flops, each with individual D inputs and Q outputs. The flip-flops are triggered by a common buffered Clock (CP) and Master Reset (MR) input, which can load and reset all flip-flops simultaneously. The device is fully edge-triggered, meaning the state of each D input is transferred to the corresponding Q output on the rising edge of the clock pulse. The Master Reset input can force all outputs to a LOW state regardless of the clock or data inputs.
