PI3USB3031XUAEX

Overview

The PI3USB3031XUAEX is a 2-channel, 1:3 multiplexer integrating a high-speed MHL/MyDP switch and two USB 2.0 High-Speed (480 Mbps) switches within a single package. It operates on a VCC range of 1.8V to 5.5V with typical current consumption of 28 µA. The device features a 6.5 GHz bandwidth for both MHL and USB paths, with typical on-resistance values of 5.5 Ω and 4.5 Ω respectively. It includes IOFF protection, 1.8V compatible control inputs, and overvoltage tolerance up to 5V without external components.

Feature Summary

Integrates MHL/MyDP and dual USB 2.0 switching capabilities in a compact form factor
Supports overvoltage tolerance on all I/O pins up to 5V without additional circuitry
Provides power-off protection to prevent current leakage when VCC is at 0V
Features 1.8V compatible digital control inputs for direct interfacing with mobile processors

Applications

PC Motherboards
Notebooks
Servers
Smartphones
Portable Instrumentation

Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm the exact package type and tape-and-reel configuration. Ensure that the selected variant matches the required mechanical dimensions and lead-free compliance standards for the target assembly process.

Selection Notes

Select this component when board space is constrained and a common connector must support multiple signal types including MHL, MyDP, and USB data. Confirm that the system voltage requirements fall within the 1.8V to 5.5V operating range and that the 1.8V logic level compatibility aligns with the host processor's GPIO specifications.

Part Context

This part belongs to the PI3USB3031 product line from Diodes Incorporated, designed specifically for mobile and portable electronics. It consolidates multiple switching functions into a single 12-pin X2-QFN package, reducing the overall bill of materials and simplifying the routing complexity for high-speed differential pairs in dense layouts.
