DG403DY-E3

Overview

The DG403DY-E3 is a CMOS analog switch manufactured by Vishay Siliconix, housed in a 16-pin SOIC surface-mount package. It integrates four independent single-pole single-throw (SPST) channels. The device supports a single supply voltage range of 13 V to 36 V or dual supplies of ±7 V to ±22 V. Key electrical specifications include a maximum on-resistance of 45 Ohms, a turn-on time of 150 ns, and a turn-off time of 100 ns. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent SPST analog switches in a compact SOIC-16 package
• Operates with single or dual power supplies for flexible system integration
• Features low on-resistance and fast switching times for signal routing

Applications

• Signal multiplexing in data acquisition systems
• Audio and video signal path switching
• Instrumentation input selection

Procurement Notes

Verify the specific suffix E3 confirms RoHS compliance when sourcing. Confirm the SOIC-16 package dimensions match the design footprint. Ensure the manufacturer is identified as Vishay Siliconix to guarantee component authenticity and traceability.

Selection Notes

Select this component when four isolated SPST switches are required in a small form factor. Compare on-resistance and leakage current against circuit requirements. Verify that the 13 V minimum single-supply voltage aligns with the available power rails in the target application.

Part Context

This part belongs to the DG403 series of CMOS analog switches from Vishay. It serves as a surface-mount alternative to through-hole variants like the DG403CP. The E3 suffix denotes environmental compliance, distinguishing it from older non-compliant versions within the same functional family.

Replacement Considerations

DG403BDY-T1-E3 offers similar functionality but includes tape-and-reel packaging options.
