Overview
The SW202FQ is a quad single-pole single-throw normally open analog switch manufactured by Analog Devices Inc. It utilizes JFET technology to provide low on-resistance and high isolation for signal routing applications. The device operates with a single supply voltage of up to 15V or dual supplies of ±15V. It is housed in a 16-CDIP ceramic package designed for through-hole mounting, ensuring robust performance in demanding environments.
Feature Summary
- Integrates four independent SPST-NO switches within a single integrated circuit
- Employs JFET technology to achieve low on-resistance and high channel isolation
- Supports flexible power configurations using either single or dual supply voltages
Applications
- Signal multiplexing and demultiplexing systems
- Data acquisition circuits requiring precise signal routing
- Audio and video signal switching networks
Procurement Notes
Verify the specific suffix requirements for your application, as packaging and temperature ranges may vary across different part number variants. Confirm that the 16-CDIP ceramic package aligns with your PCB footprint and assembly capabilities. Ensure compliance with RoHS standards if required by your manufacturing process. Cross-reference the manufacturer's official documentation to validate electrical characteristics against your system design specifications before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits that require multiple isolated signal paths controlled by a single chip. The JFET input structure makes it suitable for applications demanding minimal signal distortion and high impedance. Consider the through-hole mounting requirement during layout planning. Evaluate the ±15V dual supply capability if your system operates with bipolar signals, ensuring the power budget accommodates the specified voltage rails.
Part Context
The SW202FQ belongs to the family of discrete semiconductor analog switches produced by Analog Devices Inc. It serves as a fundamental building block for creating complex switching matrices in industrial and instrumentation equipment. The ceramic DIP package offers superior thermal stability and hermetic sealing compared to plastic alternatives, making it appropriate for high-reliability aerospace or military-grade applications where long-term durability is critical.
Replacement Considerations
Direct replacements must match the 16-CDIP package and quad SPST-NO configuration. Verify pin compatibility and electrical parameters such as on-resistance and breakdown voltage. Consult the manufacturer's substitution guide for equivalent devices with identical functional specifications.
