Disadvantages: - Limited input voltage range. - Requires external power supply within specified voltage range.

Working Principles

The SN74LS298DRG4 operates as a quad 2-input multiplexer with storage. It uses select inputs (S0-S3) to choose between four sets of input data (A0-A3 and B0-B3). The selected data is then stored in internal flip-flops until the next selection is made. The complementary output (Q̅) provides the inverse of the selected output (Q).

Detailed Application Field Plans

The SN74LS298DRG4 can be used in various applications, including:

1. Data Routing: Selecting and routing specific data inputs to desired outputs in digital systems.
2. Memory Addressing: Multiplexing address lines to access different memory locations.
3. Arithmetic Logic Units (ALUs): Controlling data flow and selection within ALUs.
4. Control Systems: Managing data selection and storage in control systems.
5. Communication Systems: Switching between different data sources or channels.
