• Can be used to select one of four data inputs (A, B, C, D) based on the select inputs
• High-speed operation allows for efficient data selection
• Low power consumption makes it suitable for battery-powered devices
• Compatible with a wide range of supply voltages (2V to 5.5V)

Advantages and Disadvantages

Advantages: - High-speed operation enables quick data selection - Low power consumption prolongs battery life in portable devices - Wide supply voltage compatibility allows for versatile applications

Disadvantages: - Limited to 4-to-1 data selection/multiplexing, not suitable for larger-scale operations - DIP-16 package may require additional space compared to surface-mount alternatives

Working Principles

The SN74AHCT158N operates based on the principles of logic gates. The select inputs (G) determine which data input (A, B, C, or D) is connected to the outputs (Y). When G is set to a specific combination, the corresponding data input is selected and passed through to the respective output.

Detailed Application Field Plans

The SN74AHCT158N can be used in various applications, including but not limited to: - Data multiplexing in microcontrollers and digital systems - Address decoding in memory systems - Signal routing in communication devices - Input selection in audio/video equipment
