Working Principles

The SN74LVTH374DBR is an octal D-type flip-flop that stores and transfers data based on clock signals. When the clock input (CLK) transitions from low to high, the data inputs (D0-D7) are latched and stored in their respective flip-flops. The stored data can then be accessed through the data outputs (Q0-Q7). The output enable (OE) pin controls whether the data outputs are active or in a high-impedance state.

The master reset (MR) pin resets all flip-flops to a known state when activated. This ensures a predictable starting point for data storage and transfer.

Detailed Application Field Plans

The SN74LVTH374DBR is commonly used in various digital systems, including but not limited to:

1. Microprocessors and microcontrollers
2. Data communication systems
3. Memory modules
4. Industrial automation equipment
5. Automotive electronics
6. Consumer electronics

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