Working Principles

The CD74AC374ME4 is a D-type flip-flop with 3-state outputs. It stores and transfers data based on the clock input signal. When the clock signal transitions from low to high, the data present at the input pins (D0-D7) is latched and stored in the flip-flop. The stored data is then available at the output pins (Q0-Q7). The output enable (OE) pin controls the state of the outputs. When OE is low, the outputs are active and reflect the stored data. When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.

Detailed Application Field Plans

The CD74AC374ME4 is commonly used in various digital systems and applications, including:

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

Its ability to store and transfer data efficiently makes it suitable for applications that require sequential data processing and storage.

Detailed and Complete Alternative Models
