Overview
The 74LVC273D,118 is an octal positive-edge triggered D-type flip-flop manufactured by Nexperia (formerly part of NXP Semiconductors). 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.
This component is particularly useful in mixed 3.3 V and 5 V environments due to its ability to interface with both voltage levels. It also includes Schmitt-trigger action at all inputs, enhancing tolerance to slower input rise and fall times.
