Bi-directional Isolator

Other Parts Discussed in Thread: ISO7631FC, ISO1541, ISO1540

I am looking for a cost effective solution for a bi-directional isolator. We have a clock signal that needs to always be in forward transmission while the data signal needs to switch between forward and reverse transmission. We would like the isolator to be able to handle up to a 10MHz clock.

A few Analog Devices parts that seem to fit are ADUM1311 or ADUM1301 but looking for a better solution from TI. What part is recommended?

Hello Jaden,

ISO7631FC is the recommended TI device.

Hello Jaden,

Just to clarify - while the ISO7631C has channels in both directions, it does not have any bi-directional channels. The only devices we have with isolated bi-directional channels are the ISO1540 and ISO1541, our I2C isolators. They only go up to 1MHz, and so may not work for your application.

Thanks,
Jason Blackman
