Overview
The DG9431EDY-GE3 is a low-voltage single SPDT analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 2.7 V to 5 V, with an absolute maximum rating of 12 V. The device features a typical on-resistance (rDS(on)) of 20 Ω at 5 V and 30 Ω at 3 V. Switching speeds include a turn-on time (tON) of 35 ns and a turn-off time (tOFF) of 20 ns at 5 V. It exhibits low leakage current, with a maximum channel-on leakage of 200 pA at room temperature. The component is housed in an SOIC-8 package and supports TTL/CMOS logic interfaces.
Feature Summary
- Low power consumption suitable for battery-operated systems
- Fast switching performance with minimal charge injection
- High ESD protection exceeding 2000 V per Method 3015.7
- TTL and CMOS compatible logic interface
Applications
- Battery operated systems
- Portable test equipment
- Sample and hold circuits
- Cellular phones
- Communication systems
Procurement Notes
Verify the part number suffix against official documentation to confirm lead-free status and RoHS compliance. Ensure the specific package variant matches design requirements. Cross-reference datasheet revision dates to validate electrical specifications. Confirm operating temperature ranges align with system constraints before procurement.
Selection Notes
Select this component for applications requiring low voltage operation between 2.7 V and 5 V. Consider the 20 Ω on-resistance and 35 ns switching speed for high-performance signal routing. Evaluate board space constraints as the SOIC-8 package offers a compact footprint compared to larger alternatives.
Part Context
The DG9431 belongs to the DG series of analog switches from Vishay Siliconix. It utilizes a low-voltage BCD-15 process technology. The device is designed for monolithic CMOS analog signal switching. It guarantees break-before-make timing to prevent signal shorting during state transitions.
Replacement Considerations
The DG9431DV-T1-E3 serves as a direct replacement when a TSOP-6 package is required instead of the SOIC-8 configuration. Both variants share identical electrical characteristics and functionality within the DG9431 family.
