Working Principles

The SN74ABT16821DLRG4 is a flip-flop with 3-state outputs. It operates based on clock signals and stores data in its internal memory. When the clock signal transitions, the input data is latched and stored in the flip-flop. The stored data can then be accessed through the output pins. The 3-state outputs allow the device to disconnect from the bus when not actively driving it, preventing conflicts with other devices connected to the same bus.

Detailed Application Field Plans

The SN74ABT16821DLRG4 is commonly used in various applications, including:

1. Data communication systems: It can be used in high-speed data communication systems to facilitate efficient data transfer between different components.
2. Microprocessor-based systems: The flip-flop can be utilized in microprocessor-based systems to store and manipulate data during processing.
3. Memory modules: It can be integrated into memory modules to provide reliable storage and retrieval of data.
