Overview
The 74AHC273PW,118 is an octal positive-edge triggered D-type flip-flop produced by Nexperia USA Inc. This integrated circuit is part of the 74AHC and 74AHCT series, designed for a wide range of applications requiring clocked storage of data. The device features clock (CP) and master reset (MR) inputs, allowing for precise control over the flip-flop states. The outputs Qn assume the state of their corresponding D inputs during the LOW-to-HIGH clock transition, and a LOW on MR forces the outputs LOW independently of clock and data inputs. This component is particularly useful in mixed voltage environments due to its overvoltage tolerant inputs and CMOS low power dissipation characteristics.
