Overview
The 74HC273D-Q100118 is an octal positive-edge triggered D-type flip-flop manufactured by NXP USA Inc. This device is part of the 74HC series and is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications. The flip-flop features clock (CP) and master reset (MR) inputs, with the outputs assuming the state of their corresponding Dn inputs on the LOW-to-HIGH clock transition. A LOW on the MR input forces the outputs LOW, independent of the clock and data inputs.
