• It allows the user to choose between two data inputs (A and B) based on the select input (C).
• The selected data is then available at the output pin (Y).
• The IC operates with high-speed CMOS logic, ensuring fast and reliable data selection.
• Schmitt-trigger inputs provide noise immunity, making it suitable for noisy environments.

Advantages and Disadvantages

Advantages: - High-speed operation - Wide operating voltage range - Low power consumption - Noise immunity due to Schmitt-trigger inputs - Versatile data selection capabilities

Disadvantages: - Limited to 2-input multiplexing - Not suitable for applications requiring more than two data inputs

Working Principles

The SN74HC158DR works by utilizing a combination of logic gates and multiplexing circuitry. When the select input (C) is set to logic low (0), the data input A is selected and passed through to the output pin (Y). Conversely, when the select input is set to logic high (1), the data input B is selected and passed through to the output. The IC operates on the principle of digital logic, where the select input determines which data input is chosen.

Detailed Application Field Plans

The SN74HC158DR can be used in various applications, including but not limited to:

1. Data routing and switching systems
2. Digital signal processing
3. Communication equipment
4. Industrial automation
5. Consumer electronics
