• Allows selection of one out of four input data lines (A0-A3) based on the select inputs
• Outputs the selected data line (Y) based on the select inputs
• High-speed operation with low power consumption
• Compatible with TTL and CMOS logic levels

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data selection and multiplexing - Low-power consumption makes it suitable for battery-powered devices - Wide supply voltage range provides flexibility in various applications - Compatibility with TTL and CMOS logic levels ensures easy integration into existing systems

Disadvantages: - Limited to 4-to-1 data selection/multiplexing, may not be suitable for larger-scale applications - Propagation delay time of 6 ns may introduce latency in certain high-speed applications

Working Principles

The SN74AHCT158DBR operates by using the select inputs (G1, G2, G3) to control which input data line (A0-A3) is connected to the output (Y). When the appropriate select inputs are activated, the selected data line is passed through to the output. The IC operates at high speed while consuming low power, making it suitable for various data selection and multiplexing tasks.
