  • Positive-edge triggered clock input (CLK)
  • Asynchronous active LOW clear input (CLR)
  • Eight individual D-type flip-flops with 3-state outputs
  • Outputs can be disabled using the output enable input (OE)

Advantages and Disadvantages

Advantages: - Low-voltage operation allows for compatibility with a wide range of systems - Clear functionality provides flexibility in data storage and transfer - 3-state outputs allow for easy integration into bus-oriented systems

Disadvantages: - Limited to octal (8-bit) data storage and transfer - Not suitable for applications requiring higher bit capacity

Working Principles

The 74LV273N,112 is a positive-edge triggered flip-flop. It stores and transfers data based on the rising edge of the clock signal (CLK). When the clear input (CLR) is activated, all flip-flop outputs are set to a low state. The data inputs (D0-D7) determine the state of each flip-flop when the clock signal rises. The output enable input (OE) controls whether the outputs (Q0-Q7) are active or in a high-impedance state.

Application Field Plans

The 74LV273N,112 IC finds applications in various digital systems where sequential logic is required. Some potential application fields include:

  1. Microcontrollers and microprocessors
  2. Data storage and transfer systems
  3. Communication systems
  4. Industrial automation
