DG406DW

Analog Switches, Multiplexers, Demultiplexers Overview

The DG406DW is a 16-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It connects one of sixteen inputs to a common output based on a 4-bit binary address. The device operates with a maximum supply voltage of 44 V and supports dual supplies up to ±20 V or a single 12 V supply. Key electrical parameters include a typical on-resistance of 50 Ω, a maximum of 125 Ω, and a transition time of 200 ns. It features low charge injection of 15 pC and an off-isolation of -69 dB. The component is housed in a 28-pin widebody SOIC package and functions within a temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs.
• TTL-compatible control inputs across the full operating temperature range.
• Epitaxial layer design prevents latchup for increased ruggedness.
• Enable function allows resetting all switches to the off state.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging and compliance status. The '-T1' suffix indicates tape and reel packaging, while its absence typically denotes tube packaging. Confirm RoHS compliance requirements for the specific procurement batch. Ensure the selected variant matches the required lead-free specifications for the intended assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a high channel count is required for single-ended signal routing. Verify that the 44 V absolute maximum rating aligns with the system's power supply rails. Consider the 125 Ω maximum on-resistance limit for applications requiring lower signal attenuation. Ensure the 28-pin widebody SOIC footprint fits the available PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG406/DG407 series of high-performance CMOS analog multiplexers. The DG406 specifically provides a 16:1 configuration, whereas the DG407 offers a dual 8:1 differential configuration. Both share similar performance characteristics and are designed for applications demanding low power dissipation and high accuracy.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG406DW-E3 is the non-tape-and-reel equivalent in the same package. DG406DN-T1-E3 serves as a PLCC-28 alternative. Cross-model substitution requires verifying pin compatibility and ensuring the replacement meets the required on-resistance and voltage ratings.
