• USB 2.0 4-Port HUB
  • Multiple transaction translator (MTT)
  • Supports USB Battery Charging 1.1 specification
  • ESD protection up to 4 KV

The U2H403F-3 is a high-performance Universal Serial Bus (USB) 2.0 Hub.

U2H403F-3 is designed with Multiple Transaction Translator (MTT) USB 2.0 HUB controller.

Multiple Transaction Translator (MTT) provides individual TT control logics for each downstream port. This is a performance better choice for USB 2.0 Hub.

The U2H403F-3 works backward compatible either when any one of downstream ports are connected to an USB 1.1 compliant device, or when the upstream port is connected to a USB 1.1 compliant host.

Technical Specifications
  • Compliant with USB 2.0 (Data Rate 1.5/12/480Mbps)
  • 4 (max.) downstream facing ports. (Three External USB A receptacle connectors + One Internal Intel block standard single USB port)
  • All downstream facing ports can handle high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) transaction.
  • Multiple transaction translator (MTT)
    • One TT per downstream port for maximum performance
