    Hi Mohankumar,

    I can support specifically for the TCA6424ARGJR. 

    TS5A23157 and TCA9548A are owned by another team. 

    Jack from my team can comment on the LSF0101DRYR model. 

    For TCA6424ARGJR, we do not have a PSPICE model for this device as it is an I2C to GPIO expander with a digital core inside. It is difficult to model all of the I/O properties of the device in PSPICE when the device requires I2C commands to set the configuration of the I/O expander. It would be best to model the input/output characteristics only by using the IBIS model provided on the product page. 

    Regards,

    Tyler

    Hi Mohankumar,

    The only supported PSPICE model for this device is the LSF0101 PSPICE Transient Model. There isn't an un-encrypted model of the device available.

    For evaluating the device under your system load conditions, there is also the LSF-EVM that can be used: www.ti.com/.../LSF-EVM
