Overview
The 74HCT273D/AUJ is an octal positive-edge triggered D-type flip-flop produced by NXP USA Inc. This integrated circuit is part of the 74HCT family and is designed for use in a variety of digital logic applications. The device features eight D-type flip-flops, each with a common clock (CP) and master reset (MR) input. The outputs of the flip-flops assume the state of their corresponding D inputs on the LOW-to-HIGH transition of the clock signal. A LOW on the master reset input forces all outputs to LOW, independent of the clock and data inputs.
