    Hi Chen,

    The TRS3232E devices are functionally the same as the MAX3232 with added IEC61000-4-2 ESD protection which is more similar to MAX3232ECUE+. 

    Here is a comparison of some of the device specs.

    Device

    Op Temp range (°C)

    ESD Protection

    MAX3232ECUE+

    0 to 70

    ±15 kV (HBM)

    ±9 kV (IEC 1000-4-2, Contact Discharge)

    ±15 kV (IEC 1000-4-2, Air-Gap Discharge)

    MAX3232CPWR

    0 to 70

    ±15 kV HBM

     

     

    MAX3232IPWR

    -40 to 85

    ±15 kV HBM

     

     

    TRS3232EPWR

    0 to 70

    ±15 kV (HBM)

    ±8 kV (IEC61000-4-2, Contact Discharge)

    ±15 kV (IEC61000-4-2, Air-Gap Discharge)

    TRS3232EIPWR

    -40 to 85

    ±15 kV (HBM)

    ±8 kV (IEC61000-4-2, Contact Discharge)

    ±15 kV (IEC61000-4-2, Air-Gap Discharge)

     

    I would recommend TRS3232EPWR as a direct replacement for MAX3232ECUE+.

    Let me know if you have any more questions.

    Regards,

    Eric
