DG406DW-T1-E3

Overview

The DG406DW-T1-E3 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, supporting dual supplies 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 400 ns, and an enable turn-on time of 400 ns. It features break-before-make switching, TTL-compatible control inputs, and an epitaxial layer to prevent latchup. The component is housed in a 28-pin widebody SOIC package and functions within a temperature range of -40 °C to +85 °C.

Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs during channel transitions.
• TTL-compatible control inputs, address lines, and enable function across the full operating temperature range.
• Epitaxial layer construction prevents latchup for increased ruggedness.
• Enable (EN) function allows resetting all switches to the off state for stacking multiple devices.

Applications

• High-speed data acquisition systems
• Audio signal switching and routing
• Automated test equipment (ATE) systems
• Avionics applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging and compliance details. The -T1 suffix indicates tape and reel packaging, while -E3 denotes lead-free and RoHS-compliant terminations. Ensure the selected variant matches the required supply chain format and environmental standards for the intended production run.

Selection Notes

Select this component when a high-channel-count multiplexer with a wide voltage range is required. The DG406 supports both single and dual supply configurations, making it suitable for diverse power environments. Verify that the 125 Ω maximum on-resistance meets the system's signal integrity requirements and that the 400 ns switching speed aligns with the application's timing constraints.

Part Context

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

Replacement Considerations

DG406DW-E3 is a tube-packaged equivalent within the same series. DG406BDW-T1-E3 is a higher-performance variant with lower on-resistance and faster switching times but requires verification of pin compatibility and parameter limits.
