Hi Team,

Our customer is using TS3USB3200 in their design and they are wondering what should they connect for the pins that are unused (Unused pin show below, circling by yellow square). Thanks!

 

Best,

    Hi Liang,

    Unused pins should be grounded using a 50 Ohm resistor.

    However, if they are not using the ID pins, are they using this mux for an MHL application? Or just to act as a 2:1 mux?

    If it is just being used as a 2:1 mux, it may be better to look at the TS3USB221 or the TMUXHS221.

    Thanks,

    Ryan
