Product details
Overview
PI3USB4000AZMEX from Diodes Incorporated is a 2:1 differential bi-directional USB 2.0 Mux/DeMux switch with 1 GHz bandwidth, 5 Ω typical ON resistance, and ±18 V tolerance on C0+/C0− pins. It provides over-voltage protection (OVP) at 4.75 V, supports 1.8 V logic control, and enables USB2.0 signal routing in Type-C smartphone docking systems.
For engineers reviewing the PI3USB4000AZMEX datasheet, PI3USB4000AZMEX pinout, PI3USB4000AZMEX application, or PI3USB4000AZMEX equivalent, key selection criteria include differential crosstalk (-35 dB @ 240 MHz), off-isolation (-30 dB @ 240 MHz), ultra-low 7 pF ON capacitance, and dual-package compatibility (ZM10 UQFN, 1.4×1.8 mm).
Technical Context
The PI3USB4000AZMEX implements a differential analog switch architecture with independent high-voltage tolerant I/O paths: C0+/C0− tolerate up to 18 V, Lx+/Lx− tolerate up to 6 V, and VDD withstands 9 V. Its OVP circuit triggers at 4.75 V and disables channels within 1 µs.
Control logic uses active-low EN and single-bit SEL to select between L0 or L1 differential paths; propagation delay is 250 ps typical, bit-to-bit skew is ≤20 ps, and power-down leakage is <1 µA with EN = high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 1 GHz – preserves USB2.0 eye diagram integrity and meets full-speed/high-speed signaling requirements. |
| ON Resistance | 5 Ω typical – minimizes insertion loss (<–0.5 dB @ 240 MHz) and maintains signal amplitude across differential pairs. |
| ON Capacitance | 7 pF – reduces loading on high-speed USB2.0 traces and avoids impedance discontinuity-induced reflections. |
| Off-Isolation | –30 dB @ 240 MHz – prevents signal coupling between inactive channel and common port during switching. |
| Crosstalk | –35 dB @ 240 MHz – ensures minimal interference between L0 and L1 differential paths when one is active. |
| OVP Threshold | 4.75 V ±0.25 V – protects downstream PHY from overvoltage events (e.g., VBUS short to D+/D−) while maintaining USB2.0 compliance. |
| Supply Range | 2.7 V to 5.5 V – supports operation from single Li-ion battery (3.3 V) or USB VBUS (5 V) without level-shifting. |
Pinout & Package
PI3USB4000AZMEX is packaged in a 10-contact Ultra-thin Quad Flat No-Lead (UQFN) package, code ZM10, measuring 1.4 mm × 1.8 mm × 0.55 mm height with 0.4 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| L0+, L0− | Differential I/O Channel 0 | USB2.0 data pair for first destination path; supports bidirectional signal flow with 6 V tolerance. |
| L1+, L1− | Differential I/O Channel 1 | USB2.0 data pair for second destination path; electrically identical to L0± with same voltage rating. |
| C0+, C0− | Common Differential I/O Port | Connects to USB2.0 upstream source (e.g., SoC D+/D−); tolerates up to 18 V for robust charging-event protection. |
| SEL | Channel Select Input | Logic-level control: SEL = low routes C0↔L0; SEL = high routes C0↔L1; compatible with 1.8 V CMOS. |
| EN | Enable Input (active-low) | Puts device into high-impedance state when driven high; reduces supply current to 1–2 µA for system power gating. |
| VDD | Positive Supply | Power rail for internal logic and switch biasing; rated for 2.7–5.5 V operation and 9 V absolute max. |
| GND | Power Ground | Reference for all analog and digital functions; must be low-inductance connection to maintain signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-high voltage tolerance | C0+/C0− withstand 18 V continuously-enables safe integration in USB Type-C systems with concurrent charging and data. |
| Integrated over-voltage protection | OVP activates at 4.75 V and disconnects channels within 1 µs-prevents damage to connected USB PHY without external components. |
| Low dynamic loading | 7 pF ON capacitance and 5 Ω Ron ensure <0.5 dB insertion loss at 240 MHz-meets USB2.0 eye mask and jitter budget. |
| Low-power standby | 1–2 µA shutdown current with EN = high-supports always-on USB detection while minimizing battery drain in portable devices. |
| 1.8 V logic compatibility | SEL and EN accept 0–5.5 V inputs with VIH ≥1.2 V-eliminates need for level shifters when interfacing with low-voltage application processors. |
Applications
| Smartphone Docking Hub | USB Type-C Alternate Mode Switching |
|---|---|
|
Use Scenario: A smartphone connects via USB Type-C to a multiport dock supporting simultaneous video (DisplayPort), data (USB2.0), and charging. IC Role / Device Role / Timing Role: Muxes USB2.0 D+/D− signals between phone and peripheral ports while isolating DP lanes; handles hot-plug and VBUS transients. Use Value: 18 V C0± tolerance and 4.75 V OVP prevent latch-up during 20 V PD charging events; 1 GHz bandwidth preserves full-speed USB2.0 link stability. |
Use Scenario: A laptop USB-C port dynamically switches between USB2.0 data, DisplayPort Alt Mode, and debug interfaces using shared physical pins. IC Role / Device Role / Timing Role: Isolates USB2.0 differential pair during DP transmission; enables clean mode transitions without signal bleed. Use Value: –35 dB crosstalk and –30 dB off-isolation suppress coupling between active DP and idle USB2.0 paths; 250 ps propagation delay avoids timing skew. |
| Tablet Peripheral Expansion | MHL Signal Protection & Routing |
|
Use Scenario: A tablet uses a USB-C expansion adapter to connect to Ethernet, SD card reader, and HDMI simultaneously. IC Role / Device Role / Timing Role: Routes USB2.0 signals from SoC to each peripheral port under SEL control; blocks fault currents during hot-swap. Use Value: Dual-channel 2:1 mux allows one USB2.0 controller to serve multiple peripherals; 6 V Lx± tolerance accommodates ESD and transient surges. |
Use Scenario: A mobile GPU outputs MHL video over USB-C while sharing D+/D− pins for auxiliary control and firmware updates. IC Role / Device Role / Timing Role: Protects MHL PHY from overvoltage on D+/D− during high-voltage charging; enables bidirectional MHL AUX channel access. Use Value: OVP activation at 4.75 V clamps transients before they reach sensitive MHL transceivers; 1 µA off-leakage prevents DC offset in analog video paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB2.0 differential multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB30E by Texas Instruments | Lower bandwidth (800 MHz), no integrated OVP, 5.5 V max C0± tolerance, 8 Ω Ron typical. | Lacks overvoltage protection and 18 V tolerance-requires external TVS diodes for Type-C charging scenarios. | Choose when cost sensitivity outweighs robustness needs and system-level OVP is already implemented. |
| FSUSB30MUX by onsemi | Same 1 GHz bandwidth, but only 6 V C0± tolerance, no OVP circuit, 6.5 Ω Ron, and no 1.8 V logic support. | Cannot survive direct VBUS-to-D+ shorts; requires external level shifters for 1.8 V SoCs. | Prefer where board space is constrained and external protection/level shifting is acceptable. |
Compared with TS3USB30E and FSUSB30MUX, PI3USB4000AZMEX uniquely integrates 18 V tolerance, 4.75 V OVP, and 1.8 V logic compatibility-reducing BOM count and enabling single-chip USB2.0 routing in rugged Type-C consumer designs.

FAQ
Does PI3USB4000AZMEX support USB 3.x SuperSpeed signals?
No. PI3USB4000AZMEX is designed exclusively for USB2.0 (480 Mbps) differential signaling with 1 GHz bandwidth. Its architecture does not support the 5 Gbps+ data rates, enhanced equalization, or dual-lane topology required for USB 3.x. Attempting to route SS TX/RX pairs will result in severe signal degradation and link failure.
Can EN and SEL be tied directly to VDD or GND without pull resistors?
Yes. EN and SEL inputs have rail-to-rail compatible thresholds (VIH ≥1.2 V, VIL ≤0.6 V) and low input current (±1 µA). Direct connection to VDD (3.3 V or 5 V) or GND is permitted and commonly used in production designs to reduce component count and simplify layout.
What is the thermal performance of the ZM10 package under continuous 5 V, 100 mA load?
In typical USB2.0 operation (no DC current flow through channels), power dissipation remains below 1.5 mW. Under worst-case DC conditions (5 V across 5 Ω Ron), junction temperature rise is <2°C above ambient in still air per JEDEC JESD51-7, confirmed by Diodes' thermal simulation data for ZM10 at 1.4×1.8 mm footprint.
Is PI3USB4000AZMEX qualified for automotive AEC-Q100 Grade 2?
No. PI3USB4000AZMEX is specified for commercial temperature range (–40°C to +85°C) and is not AEC-Q100 qualified. Diodes offers the automotive-grade PI3USB4000AQZMEX variant (with PPAP documentation and IATF 16949 manufacturing) for automotive infotainment and telematics applications requiring AEC-Q100 Grade 2 compliance.
