Working Principles

The SN74AC374DWRE4 is a D-type flip-flop that stores and transfers data based on clock signals. When the clock signal transitions from low to high, the input data is latched and stored in the flip-flop's internal memory. The stored data is then available at the output pins. The OE (Output Enable) pin controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74AC374DWRE4 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
