• Allows selection of one out of four data inputs based on the select inputs
• TTL logic compatible inputs and outputs
• Low power consumption
• High-speed operation

Advantages and Disadvantages

Advantages: - Integration of multiple multiplexers in a single package saves board space - TTL compatibility allows easy integration with existing systems - Low power consumption helps reduce overall power requirements - High-speed operation enables efficient data selection

Disadvantages: - Limited to 2-line to 1-line multiplexing functionality - Requires external enable signal for proper operation

Working Principles

The SN74LS258BNSRG4 is a quad 2-line to 1-line data selector/multiplexer. It combines four individual multiplexers into a single integrated circuit. The select inputs (A0, B0, A1, B1) determine which data input (D0-D3) is connected to the output (Y). The enable input (C) controls the operation of the multiplexer.

When the enable input is high, the selected data input is passed through to the output. When the enable input is low, the output is in a high-impedance state. The TTL logic ensures compatibility with other TTL devices.

Detailed Application Field Plans

The SN74LS258BNSRG4 finds applications in various fields, including:

1. Data communication systems
2. Digital signal processing
3. Multiplexing/demultiplexing circuits
