Description
PI5USB2546ZHEX is a USB 2.0 high‑speed data-switch/multiplexer IC from Pericom (now Renesas/Diodes). It is designed to route USB D+ and D− signals between a host controller and multiple USB devices or ports, using simple control inputs (enable/select pins) to switch or share connections. Typical use cases include USB hubs, docking stations, multi‑port sharing, and test fixtures where flexible USB routing is needed without a hub or PCIe switch.
Key points:
- Targets USB 2.0 high‑speed operation (up to 480 Mbps) with low‑loss data paths.
- Includes a straightforward control interface and protective features common to USB switches.
- ZHEX suffix indicates Pb‑free, halogen‑free packaging.
For exact channel count, pinout, voltage range, switching characteristics, and application notes, consult the official datasheet for PI5USB2546ZHEX.

Features
PI5USB2546ZHEX is a USB 2.0 switch/multiplexer device. Key features typically include:
- USB 2.0 High-Speed data switching (up to 480 Mbps per channel)
- Bidirectional, low on-resistance data paths
- Multi-channel/configurable port routing (crosspoint/mux capability)
- Built-in ESD protection on D+ and D− lines
- Port protection with current limiting and over-current/short‑circuit protection
- Hot-swappable operation with isolation when ports are off
- Control interface compatible with standard logic (5V tolerant I/O; supports simple GPIO/I2C/SPI-like control)
- Suitable for USB device/host multiplexing and hub-like applications
- RoHS-compliant ZHEX package (lead-free)
Note: exact pinout, voltages, and control interface specifics vary by revision; consult the current datasheet for precise operating ranges and package details.
