RS2255XN

Overview

The RS2255XN is a single-channel analog switch manufactured by Runic Technology, housed in a 10-MSOP surface-mount package. It functions as a SP4T (Single Pole 4 Throw) multiplexer/demultiplexer with a 4:1 circuit configuration. The device operates on a single supply voltage ranging from 2.5V to 5.5V. Key electrical specifications include a maximum on-resistance of 30 ohms and a typical channel-to-channel matching of 1 ohm. It features a -3dB bandwidth of 180MHz, with maximum switch times of 90ns for turn-on and 70ns for turn-off. Leakage current is limited to 100nA, while charge injection is specified at 6pC. The component supports an operating temperature range of -40°C to +125°C.

Feature Summary

• SP4T switching architecture enabling 4:1 signal routing within a single integrated circuit
• Low on-resistance characteristics ensuring minimal signal attenuation across the conduction path
• High bandwidth capability supporting high-frequency signal transmission applications
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Signal routing in data acquisition systems requiring multi-channel selection
• Audio signal switching and matrix routing in consumer electronics
• Instrumentation front-end multiplexing for sensor signal conditioning
• Communication equipment requiring low-distortion analog signal paths

Procurement Notes

Verify the manufacturer part number RS2255XN against official Runic Technology documentation to confirm authenticity. Ensure the ordering suffix matches the required packaging format, such as tape and reel or cut tape, as indicated in distributor catalogs. Confirm that the component meets RoHS3 compliance requirements if mandated by the target assembly process. Cross-reference the specific lot code and date code with supplier declarations to ensure traceability and quality standards are met for production integration.

Selection Notes

Select this component when a single-pole four-throw analog switch is required with a 30-ohm maximum on-resistance. The 10-MSOP package is appropriate for space-constrained surface-mount designs. Verify that the 2.5V to 5.5V single-supply operation aligns with the system power rails. Consider the 180MHz bandwidth and 100nA leakage current specifications to ensure they meet the signal integrity requirements of the intended application circuit without additional buffering.

Part Context

The RS2255XN belongs to the RS2255 series of analog switches produced by Runic Technology. This series focuses on providing cost-effective solutions for signal routing in compact electronic devices. The MSOP10 package variant offers a balance between pin count and physical footprint, facilitating automated assembly processes. It serves as a functional alternative to similar SP4T switches from other manufacturers, maintaining compatibility with standard interface voltages and control logic levels common in modern embedded systems.

Replacement Considerations

Consult official substitution guides for direct equivalents. Verify pinout compatibility and electrical parameter overlaps before integrating any alternative components into existing designs.
