Product details
Overview
PI3USB4000BZUAEX from Diodes Incorporated is a differential 2:1 USB 2.0 multiplexer/demultiplexer switch with 1 GHz bandwidth, 5 Ω typical on-resistance, and integrated over-voltage protection (OVP) triggering at 4.75 V. It supports bidirectional high-speed data routing between a common port (C0+/C0−) and two differential channels (L0+/L0− or L1+/L1−), enabling USB Type-C switching in smartphones and tablets while maintaining signal integrity and eye diagram compliance.
For engineers reviewing the PI3USB4000BZUAEX datasheet, PI3USB4000BZUAEX pinout, PI3USB4000BZUAEX application, or PI3USB4000BZUAEX equivalent, key selection criteria include OVP trigger voltage (4.75 V), channel leakage in power-down mode (<1 µA), differential crosstalk (–35 dB @ 240 MHz), and 1.8 V logic-compatible control pins (SEL/EN).
Technical Context
The PI3USB4000BZUAEX implements a single-pole double-throw (SPDT) analog switch architecture for differential USB 2.0 signals, with independent EN and SEL control logic determining channel selection and power-state behavior. Its internal OVP circuit monitors C0+/C0− continuously and forces channel disable within 1 µs when voltage exceeds 4.75 V.
It features ultra-low 7 pF on-capacitance and 0.25 ns propagation delay to preserve 480 Mbps USB 2.0 eye opening, while supporting rail-to-rail analog input range (0–5.5 V) and high-voltage tolerance: C0± up to 24 V, Lx± up to 6 V, and VDD up to 9 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 1 GHz – preserves USB 2.0 high-speed (480 Mbps) signal integrity and eye diagram compliance |
| On-resistance (Ron) | 5 Ω typ – minimizes insertion loss and voltage drop across differential paths |
| OVP trigger voltage | 4.75 V – protects downstream USB PHY from overvoltage during fast-charging events |
| Differential crosstalk | –35 dB @ 240 MHz – ensures isolation between active and inactive channels under high-frequency operation |
| Propagation delay | 0.25 ns typ – enables precise timing alignment for high-speed differential signaling |
| Supply current (normal) | 35 µA typ – enables low-power operation in battery-powered portable devices |
| Control logic voltage | 1.8 V compatible – allows direct interfacing with modern AP/GPU GPIO without level-shifting |
Pinout & Package
PI3USB4000BZUAEX is packaged in a 10-contact UQFN (ZUA10) measuring 1.5 × 2.0 mm with 0.6 mm pitch and 0.5 mm height. The package is lead-free, RoHS-compliant, and halogen-free per Diodes Incorporated's Green standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| L0+, L0− | Differential I/O Channel 0 | Primary output path selected when SEL = 0; supports ±50 mA continuous current |
| L1+, L1− | Differential I/O Channel 1 | Secondary output path selected when SEL = 1; identical electrical specs to L0 |
| C0+, C0− | Common Differential Port | High-voltage tolerant (up to 24 V); connects to USB D+/D− or MHL lanes |
| SEL | Channel Select Input | Logic-controlled SPDT selector: SEL = 0 routes C0↔L0; SEL = 1 routes C0↔L1 |
| EN | Enable Input | Active-low enable: EN = 0 activates switch; EN = 1 places all channels in Hi-Z state |
| VDD | Power Supply | 2.7–6.0 V supply; tolerates up to 9 V transient for robust system integration |
| GND | Power Ground | Reference for all analog and digital functions; requires low-impedance PCB connection |
Key Features
| Feature | Design Value |
|---|---|
| Integrated over-voltage protection | OVP triggers at 4.75 V on C0+/C0− and disables channels within 1 µs to prevent damage to connected USB PHY |
| Ultra-low on-capacitance | 7 pF typical – reduces signal distortion and maintains >1 GHz bandwidth for USB 2.0 compliance |
| High-voltage I/O tolerance | C0± withstands 24 V DC; Lx± withstands 6 V DC; eliminates need for external TVS diodes in charging-critical designs |
| Low-power standby mode | 1–2 µA quiescent current when EN = high – extends battery life in always-on mobile accessories |
| 1.8 V logic compatibility | SEL and EN accept 0–5.5 V inputs with VIH ≥ 1.2 V and VIL ≤ 0.6 V – interfaces directly with AP/GPU GPIO |
Applications

Use Value: Allows hub designers to meet USB-IF compliance without adding discrete OVP circuitry, lowering cost and complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 differential multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB30E | No integrated OVP; max C0± tolerance = 5.5 V; Ron = 6.5 Ω; bandwidth = 850 MHz | Suitable only in systems with external OVP or strict 5 V-only USB operation | Select when cost sensitivity outweighs need for on-die overvoltage protection |
| MAX14533 | Higher Ron (8 Ω typ); no C0± > 5.5 V tolerance; OVP not implemented; 1.2 V logic compatible only | Requires level shifters for 1.8 V control; unsuitable for 24 V charging scenarios | Prefer only in legacy 1.2 V logic environments where Diodes' 1.8 V compatibility is unnecessary |
Compared with TS3USB30E and MAX14533, PI3USB4000BZUAEX uniquely combines 24 V C0± tolerance, 4.75 V OVP, and 1.8 V logic support-making it the only option qualified for USB-C fast-charging coexistence in smartphones and tablets without external protection.

FAQ
What is the maximum continuous voltage the C0+/C0− pins can withstand?
The C0+/C0− pins are rated for continuous operation up to +24 V and –0.3 V, verified per Diodes Incorporated's absolute maximum ratings table. This rating applies regardless of device power state and enables direct integration into USB-C charging paths without external clamping diodes.
Does PI3USB4000BZUAEX support USB 2.0 high-speed (480 Mbps) eye diagram compliance?
Yes. With 1 GHz bandwidth, 0.25 ns propagation delay, and –35 dB crosstalk at 240 MHz, the PI3USB4000BZUAEX preserves USB 2.0 high-speed signal integrity. Diodes' datasheet includes measured eye diagrams confirming full compliance under standard test conditions.
How does the over-voltage protection (OVP) respond during a fast-rising transient?
OVP triggers when either C0+ or C0− exceeds 4.75 V, disabling all channels within 1 µs (typical). The response time is guaranteed by design and validated using 500 ps rise-time pulses per the datasheet test circuit, ensuring protection against USB PD charger transients.
Can SEL and EN be driven directly from a 1.8 V GPIO without level shifting?
Yes. SEL and EN accept logic-high inputs as low as 1.2 V (VIH min) and logic-low inputs up to 0.6 V (VIL max) across the full 2.7–5.5 V VDD range. This allows direct connection to 1.8 V AP/GPU GPIOs without external level translators.
