Overview
The STG5682QTR is a high-speed CMOS low voltage dual analog Single Pole Dual Throw (SPDT) switch or 2:1 Multiplexer/Demultiplexer fabricated in silicon gate C2MOS technology. Designed for portable applications, it operates from a single supply of 1.65V to 4.5V. Key electrical parameters include an ultra-low power consumption with maximum supply current of 0.2µA at 85°C, and a maximum ON resistance of 0.5Ω at 25°C when VCC is 4.3V. The device features distortion-free negative signal throughput down to VCC - 5.5V and provides ESD immunity exceeding JESD22 standards.
Feature Summary
- Ultra-low power dissipation suitable for battery-operated portable devices
- Distortion-free negative signal throughput capability extending below ground potential
- High ESD protection performance with latch-up immunity exceeding 300mA per JESD 17
Applications
- Portable electronic equipment requiring low voltage operation
- Signal routing in multiplexer/demultiplexer configurations
- Battery-powered systems prioritizing minimal power consumption
Procurement Notes
Verify component authenticity through authorized distribution channels due to the discontinued status indicated in public records. Confirm RoHS compliance details via the official datasheet before integration. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during assembly processes.
Selection Notes
Select this component for designs requiring sub-1V logic compatibility and minimal static power draw. The 0.5Ω ON resistance supports high-fidelity signal transmission. Verify that the operating voltage range aligns with the system's single supply constraints and that the QFN package fits the PCB layout constraints.
Part Context
The STG5682 belongs to the STG568x series of analog switches from STMicroelectronics. It shares the C2MOS fabrication process with related models but offers specific low-voltage and low-power optimizations. The 'QTR' suffix typically denotes tape and reel packaging for surface-mount assembly.
Replacement Considerations
Public data indicates the STG5682 is obsolete. No direct verified substitute part numbers are listed in the provided source material. Engineers should consult the manufacturer for end-of-life notifications or equivalent alternatives within the same product family.
