Working Principles

The 74AHCT273PW,112 is a positive-edge-triggered octal D-type flip-flop. It stores and transfers data based on the rising edge of the clock pulse. When the clock input (CP) transitions from LOW to HIGH, the data present at the D0-D7 inputs is latched and transferred to the corresponding Q0-Q7 outputs.

The clear input (CLR) is an active LOW signal that resets all flip-flops to a known state when asserted. The outputs remain in this state until a valid clock pulse is received.

Detailed Application Field Plans

The 74AHCT273PW,112 is widely used in various digital systems and applications, including but not limited to:

1. Microprocessors and microcontrollers
2. Data storage devices
3. Communication systems
4. Industrial automation
5. Automotive electronics
6. Consumer electronics
