Overview
The STG3682QTR is a high-speed CMOS low voltage dual analog SPDT switch fabricated in silicon gate C2MOS technology. It operates from a single supply of 1.65V to 4.3V, making it suitable for portable applications. The device features an ultra-low power dissipation with maximum supply current of 0.2µA at 85°C. Typical on-resistance is 4.6Ω at 4.3V and 5.8Ω at 3.0V. It provides a typical bandwidth of 800MHz on all channels and complies with USB 2.0 high-speed signal switching requirements. The package is QFN-10L.
Feature Summary
- High-speed signal switching compliant with USB 2.0 standards
- Ultra-low power consumption for battery-operated devices
- Wide operating voltage range supporting various logic levels
Applications
- Portable consumer electronics
- USB 2.0 signal routing
- Battery-powered instrumentation
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and temperature grade. Confirm that the QFN-10L package dimensions match the target PCB footprint. Check RoHS compliance status via the datasheet before finalizing procurement specifications.
Selection Notes
Select this component when dual SPDT switching with high bandwidth is required under low voltage conditions. Ensure the application voltage remains within the 1.65V to 4.3V range. Consider the 800MHz bandwidth requirement for high-frequency signal integrity. Verify thermal performance if multiple switches are active simultaneously.
Part Context
This part belongs to the STG3682 series of analog switches. It is distinct from the STG3680 which offers lower on-resistance but different packaging. The STG3692 variant provides quad switching capability instead of dual. All parts share similar low-voltage operational characteristics.
Replacement Considerations
STG3680QTR offers lower on-resistance (800mOhm) but uses a 16-QFN package. STG3692QTR provides four channels instead of two in a 16-QFN package. Verify pin compatibility and package dimensions before substituting.
