    Hi Gurmeet,

    I am not familiar with these devices, so I am going to move your post to a differenet forum. The easiest way to find out I2C I/O Expanders is to go:

    www.ti.com --> Products --> Interface --> I2C --> I2C IO Expander

    There are a total of 27 I2C expanders with and without interrupts. You can then reduce the parametric table down to ones with only 16 outputs. This results in 11 devices.

    I have used the device below before.

    TCA6416A - Low-Voltage 16-Bit I2C and SMBus I/O Expander
     
    Hope this helps!
