Working Principles

The 74LVX374MTR is a positive-edge-triggered flip-flop that stores and transfers data based on clock pulses. When the clock pulse rises from low to high, the data inputs (D0-D7) are latched and stored in the flip-flop. The stored data can then be accessed through the corresponding output pins (Q0-Q7). The output enable (OE) pin controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The 74LVX374MTR is widely used in various digital systems where data storage and transfer are required. Some specific application fields include:

1. Microcontrollers: Used for storing and transferring data between the microcontroller and external devices.
2. Communication Systems: Facilitates data buffering and synchronization in communication protocols.
3. Memory Modules: Enables efficient data storage and retrieval in memory modules.
4. Industrial Automation: Used for controlling and monitoring data flow in industrial automation systems.
5. Automotive Electronics: Provides reliable data storage and transfer in automotive electronic control units.
