PI3USB14ZHE

Analog Switches - Special Purpose Overview

The PI3USB14ZHE is a dual-channel USB switch IC manufactured by Diodes Incorporated, designed for USB 2.0 applications. It features a 4:1 multiplexer/demultiplexer circuit configuration within a 16-TSSOP surface-mount package. 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 a -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 protocol standards
• Dual-channel architecture with 4:1 mux/demux capability
• Low on-state resistance for signal integrity

Analog Switches - Special Purpose Applications

• USB interface switching
• Signal routing in USB hubs
• Peripheral connection management

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 available EDA models from the manufacturer. Ensure the 3.3V supply requirement aligns with the system power rails. Review the datasheet for any specific handling instructions despite the component's discontinued status.

Analog Switches - Special Purpose Selection Notes

Select this component only if the design accommodates obsolete parts or requires legacy support. The 815MHz bandwidth suits standard USB 2.0 speeds but may not support higher data rates. Verify that the 8 Ohm on-resistance meets the signal loss budget. Consider the 16-TSSOP package availability for assembly. Evaluate alternative modern switches if long-term supply stability is critical.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3USB series of USB switch ICs from Diodes Incorporated. It shares functional similarities with other devices in the family but is distinguished by its specific 4:1 mux configuration and 16-TSSOP packaging. The base product number is PI3USB14. It is distinct from PCIe or USB 3.0 variants in the manufacturer's portfolio.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements should be verified against current Diodes Incorporated portfolios or equivalent third-party components with matching 4:1 mux specifications.
