Working Principles

The CD74AC273EG4 is a D-type positive-edge-triggered flip-flop. It stores and outputs data based on the rising edge of the clock pulse (CP) input. The data inputs (D0-D7) are latched into their respective flip-flops when the clock signal transitions from low to high. The stored data can be cleared using the clear (CLR) input, which is active LOW.

Detailed Application Field Plans

The CD74AC273EG4 can be used in various applications that require sequential data storage and retrieval. Some potential application fields include:

  1. Digital counters
  2. Shift registers
  3. Memory address decoding
  4. Data synchronization circuits
  5. State machines

Detailed and Complete Alternative Models

  • SN74AC273: Similar functionality, different package (20-pin PDIP)
  • MC74AC273: Similar functionality, different package (20-pin SOIC)
  • 74HC273: Lower power consumption, compatible pin configuration (20-pin TSSOP)

These alternative models provide similar functionality to the CD74AC273EG4 but may have differences in package type, power consumption, or voltage compatibility.
