ISO1410: P2P dropped-in alternative for half-duplex communication?

Part Number: ISO1410
Other Parts Discussed in Thread: ISO1430, ISO1450, ISO3088, ISO1412

Team,

Because of the availability of the ISO1410 I am checking for dropped-in alternatives:

I am assume that all ISO14x0 (ISO1410 vs ISO1450 vs ISO1430) are dropped-in replacement for ISO1410. Correct?

Are there some other options that can be considered as dropped-in replacement (ie without any HW change required)?
What other options would require minimum HW changes?

Thanks in advance!

    Hi AnBer,

    Thank you for reaching out to us!
    ISO1410, ISO1430, and ISO1450 are pin2pin devices.
    The main differences are their maximum data rates, 0.5Mbps, 12Mbps, and 50Mbps. The rise/fall times and propagation delays are optimized to meet the data rate. Please refer to sections 8.13 and 8.14 in the datasheet for the details. These parameters may affect the setup and hold time of your system. Also, the power dissipation increases with the data rate described in section 8.5 in the datasheet. Using a device with a higher maximum data rate can result in higher power consumption in your system.

    For alternate devices that are pin2pin to ISO1410, you may consider ISO3088. However, they have different power supply requirements and isolation ratings than ISO1410.

    The next option that requires minor HW changes would be ISO1412. It is a full-duplex device. Its pin A is at pin 14 instead of pin 12. Also, pin Y should connect to pin A, and pin Z should connect to pin B to achieve half-duplex.

    Please note that ISO14xx is the latest family that offers best performance compared to older devices. I recommend to stay with ISO14xx device if possible.

    Regards,
