Overview
The MC74AC273DTR2G, produced by onsemi, is an octal D-type flip-flop integrated circuit. This device features eight edge-triggered D-type flip-flops, each with individual D inputs and Q outputs. It includes a common buffered Clock (CP) and an asynchronous Master Reset (MR) input, which allows for simultaneous loading and resetting of all flip-flops. This component is particularly useful in applications where true output only is required and the Clock and Master Reset are common to all storage elements.
