Functional Features

• Four select inputs (S0-S3) for channel selection
• Enable input (INH) to disable the multiplexer
• Two data outputs (Y and Z) for selected input signal transmission
• Wide operating voltage range
• Low power consumption
• Fast switching speed

Advantages and Disadvantages

Advantages: - High-speed operation allows for quick signal switching - Low power consumption reduces energy usage - Wide operating voltage range provides flexibility in various applications - Compact DIP package allows for easy integration into circuit boards

Disadvantages: - Limited number of input channels (4 in this case) - Propagation delay may affect real-time applications

Working Principles

The DG409DJ is a digital multiplexer that operates based on the select inputs (S0-S3). When a specific combination of select inputs is applied, the corresponding input signal is transmitted to the output. The enable input (INH) can be used to disable the multiplexer, preventing any signal transmission.
