Overview
The PI3USB4000AZMEX is a differential bi-directional 2:1 multiplexer/demultiplexer switch manufactured by Diodes Incorporated. It operates on a single supply voltage ranging from 2.7V to 6.0V, with an analog input/output voltage range of 0V to 5.5V. The device features a typical ON resistance (Ron) of 5Ω and a maximum of 8Ω, alongside ultra-low capacitance values of 7pF for ON state and 9pF for OFF state. It supports a -3dB bandwidth of 1GHz and includes over-voltage protection that triggers at approximately 4.75V. The component is housed in a 10-contact UQFN package measuring 1.4x1.8mm.
Feature Summary
- Ultra-high voltage tolerance allowing C0+/C0- pins to withstand up to 18V and Lx+/- pins up to 6V.
- Integrated over-voltage protection circuitry that automatically switches off channels when Vbus exceeds the threshold.
- Supports 1.8V logic levels on control pins while maintaining compatibility with standard USB 2.0 signaling.
- Provides low power consumption with typical current draw of 35µA during normal operation.
Applications
- Smart Phones
- Type-C Applications
- Tablets
- Notebook Computers
- Personal Computers
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package dimensions and reel specifications. Ensure the procurement channel is authorized to guarantee product authenticity and compliance with RoHS directives. Cross-reference the part marking codes with the datasheet to validate manufacturing dates and quality standards before integration into production lines.
Selection Notes
Select this component when designing circuits requiring high voltage tolerance on signal lines without compromising USB 2.0 signal integrity. The wide supply voltage range accommodates various system power architectures. Consider the compact 10-UQFN footprint for space-constrained mobile designs. Verify that the 1.8V logic compatibility aligns with the host controller's GPIO capabilities for proper SEL and EN pin configuration.
Part Context
This part belongs to the PI3USB4000A family of ultra-high voltage protection USB 2.0 multiplexers. It shares core electrical characteristics with variants like the PI3USB4000AZUAEX but utilizes a distinct ZM package code. The ZM package offers a slightly different physical profile compared to the ZUA variant, providing design flexibility for board layout constraints while maintaining identical functional performance.
Replacement Considerations
The PI3USB4000AZUAEX serves as a direct functional substitute within the same product family. Both parts share identical electrical specifications and pinout configurations. The primary distinction lies in the mechanical package dimensions; the ZUA package measures 1.5x2.0mm, whereas the ZM package measures 1.4x1.8mm. Designers must verify land pattern compatibility when swapping between these package types.
