Overview
The STG3680QTR is a high-speed CMOS dual analog SPDT switch or dual 2:1 multiplexer/demultiplexer bus switch fabricated in silicon gate C2MOS technology. Designed for portable applications, it operates from a single supply voltage of 1.65V to 4.3V. The device features ultra-low power dissipation with a maximum quiescent current of 0.2µA at 85°C. It offers very low on-resistance, specified as a maximum of 0.5Ω for S1 channels and 0.8Ω for S2 channels at VCC=2.7V. Key performance metrics include a typical propagation delay of 0.3ns at 3.0V and a break-before-make delay time of up to 15ns.
Feature Summary
- Break-before-make switching feature prevents signal shorting during channel transitions
- High ESD immunity exceeding 7kV Human Body Model on analog channels
- Latch-up performance exceeds 300mA per JESD 17 standard
- Digital control inputs are 4.3V tolerant and compatible with 1.8V logic thresholds
Applications
- Portable electronic devices requiring low voltage operation
- Bus switching applications in multiplexer/demultiplexer configurations
- Signal routing in systems with mixed 1.8V and 4.3V logic levels
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm the specific QFN package dimensions match the design footprint. Check for RoHS compliance status relative to environmental regulations. Ensure storage conditions adhere to the specified temperature limits to maintain device integrity prior to assembly.
Selection Notes
Select this component when break-before-make timing is critical to avoid signal contention. Verify that the required on-resistance falls within the specified ranges for the target supply voltage. Ensure the operating temperature range covers the application's environmental extremes. Consider the 35pF load capacitance requirements for AC performance validation.
Part Context
The STG3680 belongs to STMicroelectronics' low-voltage analog switch family utilizing C2MOS technology. It serves as a dual SPDT solution for signal routing in compact form factors. The QFN-16 (3x3mm) package supports surface-mount assembly for space-constrained designs. This part number represents the tape and reel variant of the device.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official replacement lists or contact the manufacturer directly for validated alternatives.
