Overview
The PI3USB4000AZUAEX-37 is a differential bi-directional 2:1 multiplexer/demultiplexer switch manufactured by Diodes Incorporated. It supports a wide input voltage range of 0V to 5.5V and features a bandwidth of 1GHz with an ultra-low ON capacitance of 7pF. The typical ON resistance is 5Ω, and propagation delay is 0.25ns. It includes over-voltage protection that triggers at 4.75V to switch off channels during fault conditions. I/O pins tolerate high voltages up to 18V on C0+/- and 6V on Lx+/-. Operating temperature ranges from -40°C to 85°C.
Feature Summary
- Differential bi-directional 2:1 Mux/DeMux architecture for USB2.0 signal routing
- Ultra-high voltage tolerance on I/O pins (C0+/- up to 18V) with integrated over-voltage protection
- Low power consumption with support for 1.8V logic control signals
- High-speed signal integrity maintained via 1GHz bandwidth and low insertion loss
Applications
- Smart Phones
- Type-C Applications
- Tablets
- Notebooks
- PCs
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The standard datasheet lists 'X' as the tape and reel suffix. Confirm whether the '-37' suffix denotes a specific manufacturing lot code, regional variant, or custom packaging configuration not explicitly detailed in the general product specification.
Selection Notes
Select this component when designing circuits requiring high voltage tolerance on data lines alongside standard USB2.0 signaling. Ensure the application environment operates within the specified -40°C to 85°C temperature range. Verify that control logic levels are compatible with the 1.8V support requirement for SEL and EN pins.
Part Context
This device belongs to the PI3USB4000A family of ultra-high voltage protection USB2 mux/demux switches. It is designed to protect downstream components from voltage spikes while maintaining signal integrity for high-speed data transmission. The ZUA package provides a compact surface-mount solution suitable for space-constrained portable electronics.
Replacement Considerations
Direct replacements include other models within the PI3USB4000A series, such as the PI3USB4000AZMEX, which utilizes a different UQFN package footprint. Cross-referencing pin compatibility and electrical characteristics is essential when substituting packages.
