The TUSB2514B is a 4-port Hi-Speed USB hub that supports USB Hi-Speed (480Mbps) and Full-Speed (12Mbps) connections on the upstream port. The device also provides USB Hi-Speed, Full-Speed, or Low-Speed (1.5Mbps) connections on the four downstream ports. The TUSB2514B hardware-based state machine eliminates firmware injection risks, enabling secure deployment in enterprise and datacenter applications without an external microcontroller.

All four downstream ports comply with the USB Battery Charging Specification Rev. 1.2. Charging Downstream Port (CDP) mode is supported when the upstream port is connected; DCP mode is the final fallback when the upstream port is not connected and other charging modes are disabled or unsupported. Each port supports individual overcurrent detection and per-port or ganged power switching.

The TUSB2514B operates without an external EEPROM using pin-strap configuration. Pin-strap selectable features include per-port battery charging, port enable/disable, and activity indicators.

For advanced customization, the TUSB2514B supports an I²C EEPROM or SMBus target interface to configure the Vendor ID (VID), Product ID (PID), USB channel polarity, and additional downstream port behavior.
