Overview
The DG9432DQ-T1-E3 is a dual single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 2.7 V to 12 V and features an MSOP-8 surface-mount package. The device provides two independent channels with a maximum on-resistance of 30 Ohms and supports a DC switch current of 10 mA. Switching performance includes a maximum turn-on time of 35 ns and a maximum turn-off time of 18 ns. The component functions within a temperature range of -40°C to +85°C, with a power dissipation rating of 320 mW.
Feature Summary
- Dual SPST configuration for independent signal routing
- Low on-resistance for minimal signal attenuation
- Compatible with low-voltage single-supply operation
Applications
- Battery-powered portable equipment
- Communication systems
- Instrumentation and control circuits
Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted, and Mouser indicates non-sale in certain regions. Verification of current stock status and alternative sourcing through authorized distributors is required before integration into new designs.
Selection Notes
Select this part for applications requiring dual isolated switching paths within a compact MSOP-8 footprint. Ensure the design accommodates the 10 mA DC switch current limit and 30 Ohm on-resistance. Verify that the 2.7 V to 12 V supply range aligns with system power rails.
Part Context
Part of the DG series of analog switches from Vishay Siliconix, designed for general-purpose signal switching. The DG9432 variant specifically offers two SPST channels, distinguishing it from multiplexer or quad-channel counterparts in the same family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineering change orders may be necessary to adopt equivalent components from other manufacturers.
