    Hi Bruce,

    The Tj spec is not included in this datasheet. Is it possible to use the upgraded version of this device - TCA9536? Tj(max) = 150C for this device. 

    For Pd - which I assume is power dissipation. There is no spec for Pd because it is dependent on the loading configuration on P0 - P3 GPIO pins. Different applications source/sink different amounts of current through the I/O expander which would affect Pd. 

    This e2e has a fairly good assessment on calculating pd for the TCA6424A. Let me know if this helps any.

    Regards,

    Tyler
