This is useful for various applications like particle (*ie smoke*) detection

we recommend keeping the sum of the input and output voltages below 55 V

serial and I2C (\"Wire\") connections

It offers adaptive data communication rates from 300 to 921

But, hey, we're engineers, and we like to push the limits of technology, right? So why not try to have I2C run over a meter long cable, or even longer? Well, if you try to do that you'll quickly find that the length of the cable adds capacitance and resistance that slows down the open drain pullups used in I2C, making it hard to use 100KHz+
