Overview
The 74LVC273DB,118, manufactured by Nexperia USA Inc., is an octal positive-edge triggered D-type flip-flop. This device is part of the 74LVC series and is designed for use in a variety of logic applications. It features clock (CP) and master reset (MR) inputs, making it versatile for different operational requirements. The flip-flop outputs 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, independent of clock and data inputs. This component is suitable for mixed 3.3 V and 5 V environments due to its input compatibility with both voltage levels.
