Overview
The 74LVC273PW/AUJ, produced by Nexperia (formerly part of NXP USA Inc.), is an octal positive-edge triggered D-type flip-flop. This device is designed to operate within a wide supply voltage range from 1.2 V to 3.6 V, making it versatile for various applications. It features clock (CP) and master reset (MR) inputs, allowing for precise control over the flip-flop's state. The outputs (Qn) assume the state of their corresponding D inputs during the LOW-to-HIGH clock transition, and a LOW on the MR input forces the outputs LOW regardless of the clock and data inputs.
