ISOW1432: Optical Isolation

Mark Philip Felipe
Genius 10830 points
Part Number: ISOW1432
Other Parts Discussed in Thread: ISOM8110

Tool/software:

Hi Team, my customer wants an isolator that fits their application.

We are using a standard called NMEA, for which optical isolation is required for RS-422
 
Hoping for some inputs.
Thank you.

    Hi Mark,

    TI Isolation portfolio does not have any optical isolation-based solution

    ISOW1432 is SiO2 based reinforced isolation and is not Optical.

    I do not know what the NMEA 0183 standard actually specifies, but in 1983, optical isolation was the only choice.

    The ISOW1432 behaves like a standard RS-422 receiver, and you should be able to use it. If there is a receiver circuit with a phototransistor optocoupler, then it can be replaced with the ISOM8110.
