Product details
Overview
PI3USB4000DZUAEX from Diodes Incorporated is a differential 2:1 bidirectional USB 2.0 multiplexer/demultiplexer switch with 1 GHz bandwidth, 5 Ω typical ON-resistance, 7 pF ON-capacitance, and integrated over-voltage protection (OVP) triggering at 4.75 V on C0+/C0− pins. It supports 2.7–5.5 V supply, 1.8 V logic-compatible control inputs, and operates across –40°C to +85°C for smartphone USB-C port switching and MHL signal routing.
For engineers reviewing the PI3USB4000DZUAEX datasheet, PI3USB4000DZUAEX pinout, PI3USB4000DZUAEX application, or PI3USB4000DZUAEX equivalent, key selection criteria include differential channel isolation (–30 dB @ 240 MHz), crosstalk suppression (–35 dB @ 240 MHz), propagation delay (0.25 ns typ), ultra-low power consumption (35 µA typ), and 24 V tolerance on C0+/C0− I/O pins.
Technical Context
The PI3USB4000DZUAEX implements a single-pole double-throw (SPDT) differential analog switch architecture with independent EN and SEL control logic. Its OVP circuitry monitors C0+/C0− voltage in real time and disables channel conduction within 1 µs when exceeding 4.75 V, preventing damage during high-voltage charging events.
It maintains USB 2.0 High-Speed (480 Mbps) signal integrity via matched differential paths (L0+/L0− and L1+/L1−), low Ron flatness (0.2–0.5 Ω), and sub-20 ps bit-to-bit skew. The REF pin requires a 1 µF/25 V decoupling capacitor tied to GND to stabilize internal biasing under transient overvoltage conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 1 GHz – preserves USB 2.0 eye diagram integrity and meets HS compliance without equalization. |
| ON Resistance | 5 Ω (typ) – minimizes insertion loss and voltage drop across differential data paths. |
| ON Capacitance | 7 pF – reduces loading on high-speed USB traces and maintains impedance matching. |
| OVP Threshold | 4.75 V – triggers immediate channel shutdown to protect downstream PHY from 24 V-tolerant C0+/C0− surges. |
| Propagation Delay | 0.25 ns (typ) – ensures minimal timing skew between D+ and D− signals in active path. |
| Off-Isolation | –30 dB @ 240 MHz – suppresses coupling from disabled channel into active USB link. |
| Crosstalk | –35 dB @ 240 MHz – prevents interference between L0 and L1 differential pairs during switching. |
| Supply Current | 35 µA (typ) – enables low-power operation in battery-powered mobile devices with no standby penalty. |
Pinout & Package
PI3USB4000DZUAEX is housed in a 10-contact UQFN package (ZUA code), measuring 1.5 × 2.0 mm with 0.6 mm pitch and 0.5 mm height. The package is lead-free, halogen-free, and RoHS 3 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| L0+, L0− | Differential I/O Channel 0 | Primary output path for USB 2.0 data when SEL = 0; rated for ±6 V continuous operation. |
| L1+, L1− | Differential I/O Channel 1 | Secondary output path when SEL = 1; identical voltage rating and signal integrity specs as L0. |
| C0+, C0− | Common Differential Input | 24 V-tolerant input pair accepting USB-C D+/D−; triggers OVP if either exceeds 4.75 V. |
| SEL | Channel Select Control | Logic-level input (0 = route C0→L0; 1 = route C0→L1); compatible with 1.8 V CMOS drivers. |
| EN | Enable/Power-Down Control | Active-high input; when high, forces all channels into high-impedance off-state with <1 µA leakage. |
| REF | Bias Reference Node | Must be decoupled to GND with 1 µF/25 V capacitor; stabilizes internal OVP comparator reference. |
| VDD | Positive Supply Rail | 2.7–5.5 V input powering analog core and control logic; tolerant to 6 V absolute max. |
| GND | Power Ground | Reference for all analog and digital functions; must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Differential 2:1 Mux/DeMux | Enables dynamic USB-C port sharing between host and peripheral roles without signal degradation. |
| 24 V Tolerance on C0+/C0− | Allows direct integration into USB-C PD charging paths where D+/D− may experience up to 24 V transients. |
| Integrated OVP at 4.75 V | Prevents latch-up or damage during accidental VBUS short-circuit events by disabling channel conduction in ≤1 µs. |
| Ultra-Low Crosstalk (–35 dB) | Ensures clean signal routing in multi-port designs where adjacent L0/L1 paths share PCB space. |
| 1.8 V Logic-Compatible Control | Eliminates level-shifting requirements when interfacing with modern AP/SoC GPIOs operating at 1.8 V. |
| Off-Protection Leakage Limit | Guarantees <1 µA leakage current when powered down (EN = high), preserving battery life in sleep mode. |

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 | Lower bandwidth (800 MHz), no integrated OVP, 6 V C0+/C0− tolerance only. | Suitable for basic USB 2.0 muxing without high-voltage charging scenarios. | Select when OVP and 24 V tolerance are not required and cost sensitivity outweighs robustness needs. |
| MAX14533 | Higher Ron (8 Ω typ), no OVP, 1.8 V logic support absent; requires 3.3 V control. | Targeted at industrial USB hubs where extended temperature range is prioritized over consumer-grade protection. | Choose only if legacy 3.3 V control infrastructure exists and 24 V fault immunity is handled externally. |
Compared with TS3USB30E and MAX14533, PI3USB4000DZUAEX uniquely combines 24 V C0+/C0− tolerance, 4.75 V OVP, 1 GHz bandwidth, and 1.8 V logic compatibility-making it the only option for USB-C PD-aware mobile device designs requiring integrated fault protection and minimal BOM count.

FAQ
What is the purpose of the REF pin and how must it be connected?
The REF pin provides the internal reference voltage for the over-voltage protection comparator. It must be decoupled to GND using a 1 µF ceramic capacitor rated for ≥25 V, placed as close as possible to the pin. Failure to do so risks OVP malfunction during transient events on C0+/C0−, potentially allowing damaging voltages to pass through.
Can PI3USB4000DZUAEX operate with a 1.8 V supply voltage?
No-the minimum VDD is 2.7 V per the Recommended Operating Conditions table. However, its SEL and EN control pins accept 1.8 V logic levels (VIH ≥ 1.2 V, VIL ≤ 0.6 V), enabling direct interface with 1.8 V GPIOs from application processors without level shifters.
How does the OVP feature respond when C0+ reaches 5.5 V while the device is enabled?
When either C0+ or C0− exceeds 4.75 V, the internal OVP circuit disables both L0 and L1 channel paths within 1 µs (typical tOVP), forcing them into high-impedance state. During this event, IDD drops to 35 µA (OVP mode current), and no signal passes between C0 and Lx pins until voltage falls below threshold.
Is the PI3USB4000DZUAEX qualified for automotive applications?
Per the datasheet, PI3USB4000DZUAEX is not AEC-Q100 qualified. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing-customers needing such qualification must contact Diodes directly for custom part numbers and certification documentation.
