Functional Features

• High-speed operation allows for efficient signal routing.
• Low-power consumption makes it suitable for battery-powered devices.
• Wide supply voltage range enables compatibility with various systems.
• 8-input multiplexer provides flexibility in selecting input signals.
• Output signal is buffered and can drive standard CMOS or TTL logic.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - Wide supply voltage range - Flexible input selection

Disadvantages: - Limited to 8 inputs - Requires external power supply

Working Principles

The DG418CY operates by using control signals to select one of the eight input signals and forwarding it to the output pin. The selection is controlled by the binary combination applied to the control pins. The selected input signal is then buffered and available at the output pin.

Detailed Application Field Plans

The DG418CY can be used in various applications, including but not limited to: - Data communication systems - Digital audio equipment - Industrial automation - Test and measurement instruments - Consumer electronics
