DG9431DY-E3

Overview

The DG9431DY-E3 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 and features a maximum on-resistance of 30 Ω at 5 V. The device supports a continuous current of 20 mA with a maximum power dissipation of 400 mW in the SOIC-8 package. Switching times are specified as 75 ns for turn-on and 50 ns for turn-off at 5 V. It includes over 2000 V ESD protection, low charge injection of 1 pC, and maintains TTL/CMOS logic compatibility.

Feature Summary

Low-voltage operation suitable for portable applications
High-speed switching with minimal charge injection
Robust electrostatic discharge protection
TTL and CMOS logic interface compatibility

Applications

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

Procurement Notes

Verify the component against the official Vishay datasheet Document Number 70831 to confirm specifications. Ensure the ordering suffix matches the required lead-free RoHS compliance status. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement.

Selection Notes

Select this component when a single SPDT configuration is required within a low-voltage environment. The SOIC-8 package provides surface-mount convenience while maintaining high performance. Consider the 30 Ω on-resistance and 20 mA current limits to ensure they align with the specific signal path requirements of the target circuit design.

Part Context

This device belongs to the DG9431 series of low-voltage analog switches. It utilizes Vishay's BCD-15 process technology to achieve high performance in a compact form factor. The product line emphasizes efficiency for battery-powered devices, offering break-before-make timing and epitaxial layer latchup prevention.

Replacement Considerations

Check for direct equivalents such as the DG9431DV-T1-E3 if a TSOP-6 package is preferred. Verify pinout compatibility and electrical parameters against alternative SPDT switches from other manufacturers to ensure seamless integration without redesigning the surrounding circuitry.
