DG9431DY

Overview

The DG9431DY is a single-pole/double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 2.7 V to 12 V. The device features a maximum on-resistance of 50 Ω at 5 V and 80 Ω at 3 V, with a typical turn-on time of 35 ns and turn-off time of 20 ns. It offers low leakage current, typically 100 pA, and minimal charge injection of 1 pC. The component is housed in an SOIC-8 surface-mount package and supports operation across a temperature range of -40 °C to +85 °C.

Feature Summary

Low-voltage operation suitable for portable battery-powered systems
Fast switching speeds with guaranteed break-before-make timing
TTL and CMOS logic compatible input interface
High electrostatic discharge protection exceeding 2000 V

Applications

Battery operated systems
Portable test equipment
Sample and hold circuits
Cellular phones
Communication systems

Procurement Notes

Verify the specific ordering suffix when purchasing. The base model DG9431DY may contain lead terminations. For RoHS compliance and lead-free specifications, confirm the presence of the -E3 suffix in the part number. Ensure the package type matches the required board layout, as this variant utilizes the SOIC-8 footprint rather than the TSOP-6 option.

Selection Notes

Select the DG9431DY for applications requiring a single SPDT switch with low power consumption and high accuracy. The device is optimized for space-constrained designs due to its small physical size. Consider the maximum on-resistance limits under specific load conditions and verify that the operating voltage remains within the 2.7 V to 12 V range for optimal performance.

Part Context

This component belongs to the DG series of low-voltage analog switches produced by Vishay Siliconix. The series utilizes a BCD-15 process technology to achieve high performance in a monolithic CMOS structure. The DG9431 specifically targets single-channel switching needs, offering a balance between speed, resistance, and power efficiency compared to higher-channel variants.

Replacement Considerations

The DG9431EDY-GE3 is a documented alternative part number within the same product family. Verify pin compatibility and electrical specifications before substitution. Other devices in the DG series may offer different channel counts or package options but should be evaluated against the specific requirements of the original design.
