PI3USB14LEX

Analog Switches - Special Purpose Overview

The PI3USB14LEX is a dual-channel USB switch IC designed for USB 2.0 applications, manufactured by Diodes Incorporated. It features a 4:1 multiplexer/demultiplexer circuit configuration within a 16-TSSOP package (0.173 inch width). The device operates on a single 3.3V supply voltage and supports an operating temperature range of -40°C to +85°C. Key electrical parameters include an -3dB bandwidth of 815MHz and a maximum on-state resistance of 8 Ohms. This component is classified as obsolete with RoHS3 compliance.

Analog Switches - Special Purpose Feature Summary

• Supports USB 2.0 signal switching and routing
• Integrates dual channels with 4:1 multiplexing capability
• Operates at low voltage with high bandwidth performance

Analog Switches - Special Purpose Applications

• USB signal switching
• Data routing in USB host or device interfaces

Analog Switches - Special Purpose Procurement Notes

Verify the obsolete status and RoHS3 compliance before integration. Confirm the 16-TSSOP package dimensions match the design footprint. Check for valid PCN documentation regarding the end-of-life notification dated March 31, 2015. Ensure sourcing from authorized distributors to avoid counterfeit components.

Analog Switches - Special Purpose Selection Notes

Select this component for designs requiring dual-channel USB 2.0 switching with a 4:1 mux/demux topology. Verify that the 3.3V supply requirement aligns with the system power architecture. Consider the 8-Ohm on-resistance and 815MHz bandwidth limits for signal integrity requirements. Evaluate alternative active parts if long-term availability is critical due to the obsolete status.

Analog Switches - Special Purpose Part Context

The PI3USB14LEX belongs to the PI3USB series of USB switch ICs from Diodes Incorporated. It shares the base product number PI3USB14. The 'LE' suffix typically denotes specific packaging or environmental compliance variations within the family, such as the TSSOP package and RoHS3 status. It is distinct from other PI3USB variants like the PI3USB102ZLEX which may have different configurations or pinouts.

Analog Switches - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status, direct replacements should be verified against current Diodes Incorporated portfolios or equivalent third-party components with matching 16-TSSOP packages and USB 2.0 specifications.
