Overview
The STG3684AQTR is a dual single-pole double-throw (SPDT) analog switch manufactured by STMicroelectronics. It operates on a single supply voltage ranging from 1.65 V to 4.3 V, making it suitable for low-voltage applications. The device features two independent channels with a maximum on-resistance of 500 mOhms and a typical power-down leakage current of 50 nA. It supports fast switching speeds with a maximum turn-on time of 55 ns and a turn-off time of 30 ns. The component is housed in a compact QFN-10 package and is rated for operation within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Dual SPDT configuration providing independent signal routing capabilities
- Low voltage operation compatible with modern portable electronics
- High-speed switching performance for data transmission applications
- Ultra-low power consumption in the disabled state
Applications
- Portable multimedia devices requiring signal path switching
- Battery-powered equipment needing low standby current
- Communication systems utilizing low-voltage logic interfaces
Procurement Notes
Verify the specific suffix 'QTR' against official STMicroelectronics documentation to confirm tape-and-reel packaging and automotive-grade qualification status. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to validate parameter accuracy before integration into production designs.
Selection Notes
Select this component when designing circuits that require dual signal paths under 4.3 V supplies. Compare the 500 mOhm on-resistance against load requirements to ensure minimal signal attenuation. Verify that the QFN-10 footprint aligns with PCB layout constraints and thermal management strategies for the intended enclosure design.
Part Context
This part belongs to the STG3684A family of low-voltage analog switches. It shares functional similarities with other members of the series but may differ in packaging or qualification grades. The 'A' designation typically indicates an advanced version within the product line, offering optimized electrical characteristics compared to earlier iterations.
Replacement Considerations
Direct substitutes include the STG3684AUTR for standard commercial grade applications. Check for pin-compatible alternatives from other manufacturers if supply chain constraints exist. Ensure any replacement maintains the same voltage range and package dimensions to avoid redesign efforts.
