PI5USB2546ZHEX

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.

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.

- Pin count: 28 pins (28-pin QFN, ZHEX package)
- Function: USB 2.0 high-speed switch/multiplexer for the USB differential data lines (D+/D−), used to route/select between USB ports (port switching with ESD protection).

- Manufacturer: Renesas Electronics Corporation. The PI5USB2546ZHEX is from the PI5 USB family, originally from Pericom Semiconductor, which Renesas acquired.
- What kind of company: Renesas is a Japanese multinational semiconductor company that designs, manufactures, and markets a broad range of ICs and microchips, including microcontrollers, analog/power devices, and interface/bridge products.

- USB 2.0 data-path switch/mux for four ports
- USB hubs and multi-port docking stations
- USB switch boxes and KVM-like devices
- USB On-The-Go (OTG) and dual-host/host-switching applications
- Embedded, industrial and automotive USB interfaces requiring flexible routing and low power
Note: PI5USB2546ZHEX is used where flexible USB port routing and controlled data-path switching are needed.

PI5USB2546ZHEX comes in a 16‑pin QFN package with an exposed pad (QFN‑16, typically 4x4 mm).
