    Zhengqing,

    TI uses suffix letters to mean several different things depending on the device so it is good to ask what it means.  For this example the TS5A3159a is a new device revision that added a new BGA package and new powered off protection feature (Hi-Z when Vcc = 0V).  You will also notice that this new protection feature comes at the cost of some leakage current.

    Thank you,

    Adam
