DG405DY-T1-E3

Overview

The DG405DY-T1-E3 is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It serves as an enhanced replacement for the legacy DG405 series, offering superior performance metrics suitable for portable and battery-operated applications. The device features four single-pole single-throw (SPST) switches within a 16-pin narrow SOIC package. Key electrical parameters include a maximum on-resistance of 23 ohms, a typical turn-on time of 100 nanoseconds, and a continuous current capacity of 30 mA per terminal. It supports a wide dynamic range with a peak-to-peak voltage blocking capability of up to 30 V and operates reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes proprietary high-voltage silicon gate process technology to ensure robust switching performance and high voltage ratings.
• Provides break-before-make timing in SPDT configurations to prevent signal shorting during state transitions.
• Maintains flat on-resistance characteristics across the full ±15 V analog signal range for consistent signal integrity.

Applications

• Audio and video signal routing and switching
• Sample-and-hold circuits requiring fast settling times
• Test and measurement equipment interfaces
• PBX and PABX communication systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and check for End-of-Life notifications prior to finalizing procurement plans. Ensure supply chain stability for long-term production requirements.

Selection Notes

Select this component when low power consumption and high speed are critical for portable designs. Compare on-resistance and leakage current specifications against alternative CMOS switches if strict linearity or ultra-low noise is required. Verify package compatibility with existing PCB footprints before integration.

Part Context

This part belongs to the DG40x family of analog switches from Vishay Siliconix. It represents an evolution of the classic DG405 design, integrating modern manufacturing processes to improve speed and power efficiency while maintaining pin-out compatibility for easier upgrades in existing hardware architectures.

Replacement Considerations

Direct functional substitutes may include other Vishay DG series parts or equivalent CMOS analog switches from manufacturers like Analog Devices or Texas Instruments. Verify pin compatibility and electrical parameter margins before substituting.
