DG407DW

Analog Switches, Multiplexers, Demultiplexers Overview

The DG407DW is a dual 8-channel high-performance CMOS analog multiplexer manufactured by Vishay Siliconix. It selects one of eight differential input pairs to a common differential output using a 3-bit binary address. The device operates with supply voltages ranging from ±5 V to ±20 V, or a single supply up to 44 V. Key electrical parameters include a maximum on-resistance of 125 Ω, a transition time of 450 ns, and charge injection of 20 pC. It features TTL-compatible control inputs and an enable function for stacking multiple devices.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs during channel transitions.
• Bilateral channels conduct current equally in both directions and block voltages up to the power supply rails when off.
• TTL compatible digital decode circuitry allows direct interfacing with standard logic families across the full operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Applications

• High-speed data acquisition systems
• Audio signal switching and routing
• Automatic test equipment (ATE) systems
• Medical instrumentation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against the manufacturer's ordering information to confirm package type and compliance status. The base model designation indicates a wide-body SOIC package. Confirm RoHS compliance requirements if lead-free terminations are mandatory for the assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring differential signal routing with low charge injection. Ensure the supply voltage does not exceed the 44 V absolute maximum rating. Verify that the required number of channels fits within the dual 8:1 configuration rather than the single-ended 16:1 alternative.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG406/DG407 series of monolithic CMOS analog multiplexers. It serves as a drop-in replacement for older DG506A and DG507A series devices while offering improved performance metrics such as lower on-resistance and faster transition times due to the advanced silicon-gate process.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG406DW-E3 is the single-ended 16-channel variant within the same family. DG407DN-T1-E3 offers the same functionality in a PLCC-28 package. Cross-reference with DG507A for legacy compatibility checks.
