I'm looking for a digital isolator that can be used as a direct replacement for an optocoupler. The output should be open drain, but without any secondary power requirements. Do we have a part like this?
For the input I would ideally like to have something with lower input power than a standard optocoupler.

Thank you Koteshwar.
I can do some loop tuning with the digital output, but the real problem with the ISO121x is the high forward voltage. A typical opto starts conducting at 1V.
This is the device we are competing, to give you an idea of the specs i need. Secondary requires power, but the primary behaves exactly as a regular opto.
