Overview
The STG3820BJR is a high-speed CMOS low-voltage quad analog DPDT switch or 2:1 multiplexer/demultiplexer fabricated in silicon gate C2MOS technology. It operates from 1.65 V to 4.3 V, making it suitable for portable applications. The device features an integrated fail-safe function to withstand overvoltage conditions when powered off. Key electrical parameters include an ultralow power dissipation of 1 μA (max) at 85 °C and a low ON resistance of 5.4 Ω at 4.3 V and 6.6 Ω at 3.0 V (both at 25 °C). It offers a typical bandwidth of 800 MHz on all channels and complies with USB 2.0 high-speed signal switching requirements.
Feature Summary
- Integrated fail-safe function protects against overvoltage during power-off states
- High ESD immunity with protection circuits against static discharge and transient excess voltage
- Fast switching speed with break-before-make delay time for reliable signal routing
- Ultralow power consumption suitable for battery-operated portable devices
Applications
- Portable electronic equipment requiring low-voltage signal switching
- USB 2.0 high-speed data line protection and switching
- Battery-powered consumer electronics systems
Procurement Notes
Verify the specific suffix BJR corresponds to the required tape-and-reel packaging configuration as defined by the manufacturer's official documentation. Confirm that the operating voltage range and interface compatibility align with the target system design before procurement. Ensure compliance with RoHS directives if applicable to the intended market.
Selection Notes
Select this component when a quad SPDT or dual DPDT analog switch is needed within a 1.65 V to 4.3 V supply range. Consider its 800 MHz bandwidth for high-speed digital signal routing. Evaluate the 5.4 Ω ON resistance at 4.3 V for signal integrity requirements. Verify that the flip-chip package fits the PCB layout constraints.
Part Context
The STG3820 belongs to STMicroelectronics' family of low-voltage analog switches. It utilizes C2MOS technology to achieve high speed and low power consumption. This series is designed for applications where space and energy efficiency are critical, such as mobile phones and handheld devices.
Replacement Considerations
Consult official STMicroelectronics documentation for verified cross-reference part numbers. Ensure any substitute maintains the same voltage range, package type, and electrical characteristics.
