The 74HC273D is a high-speed CMOS octal D-type flip-flop with a common clock (CP) and master reset (MR) input. This device is designed to provide eight identical D-type flip-flops in a single package.

• Function: The outputs ( Q n​ ) assume the state of their corresponding data inputs ( D n​ ) on the positive-going edge of the clock pulse (CP).

• Reset Function: The master reset (MR) input is active LOW. A LOW signal on MR forces all outputs ( Q 0​  through  Q7​) to a LOW logic level, regardless of the clock or data inputs.

• The 74HC273D is an octal positive-edge triggered D-type flip-flop. While historically produced by NXP Semiconductors (and its predecessor Philips Semiconductors), Nexperia has acquired this part of the business, and they are now the primary source for this datasheet. The D suffix typically denotes the SOIC (Small Outline Integrated Circuit) package.

  Here is a summary of the datasheet information for the 74HC273D:
