Overview
The DG9434DQ-T1-E3 is a dual single-pole single-throw (SPST) 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 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. Power dissipation is rated at 320 mW, with a maximum supply current of 1 uA. It functions within an operating temperature range of -40°C to +85°C and is housed in an MSOP-8 surface-mount package.
Feature Summary
- Dual SPST configuration for independent signal path control
- Low power consumption suitable for battery-operated systems
- Fast switching speeds for high-frequency signal routing
Applications
- Signal routing in portable instrumentation
- Audio and video signal switching
- Data acquisition systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for end-of-life notices as availability may be restricted. Ensure the MSOP-8 package matches design requirements. Validate electrical parameters against specific application needs before integration.
Selection Notes
Select this component when dual isolated signal paths are required within a compact footprint. The low supply current makes it appropriate for energy-efficient designs. Verify that the 30 Ohm on-resistance meets signal integrity requirements. Ensure the 12 V maximum voltage rating aligns with system supply levels. Consider thermal management given the 320 mW power dissipation limit.
Part Context
This part belongs to the DG series of analog switches from Vishay Siliconix. It complements other devices like the DG201HSDQ-T1-E3 and DG2031DQ-T1-E3 in the product line. The series offers various channel counts and configurations for different signal processing needs.
Replacement Considerations
Publicly documented recommended alternatives include the DG92 series. Verify pin compatibility and electrical specifications before substitution. Cross-reference datasheets for exact parameter matching.
