• The enable input (E) allows the user to control the operation of the IC, enabling or disabling the data selection process.
• The select inputs (S0, S1, S2) determine which data input is selected and routed to the output.

Advantages and Disadvantages

Advantages

• High-speed operation allows for efficient data selection in time-critical applications.
• Low power consumption makes it suitable for portable and battery-powered devices.
• Versatile functionality with eight data inputs and one output.
• Compact 16-pin DIP package offers ease of integration into various circuit designs.

Disadvantages
