Overview
The 74LVC273PW-Q100J, produced by Nexperia USA Inc., is an octal positive-edge triggered D-type flip-flop. This device is designed with clock (CP) and master reset (MR) inputs, making it versatile for various digital circuit applications. The outputs Qn assume the state of their corresponding D inputs during the LOW-to-HIGH clock transition, meeting the set-up and hold time requirements. A LOW on the MR input forces the outputs LOW, independent of the clock and data inputs. This feature is particularly useful in mixed 3.3 V and 5 V environments, allowing the device to act as a translator between different voltage levels.
