Hello,
Can we use SN65HVD3080E and SN65HVD485E with the photocoupler?
They using the photocoupler to D,DE,RE,R pins.
Signal rate:19.8kbps~100kbps
Photocoupler parts number is TLP293.
I think that we can use the photo coupler for R output.
However regarding D,DE and RE input, it is difficult to using photocoupler due to the internal resister values are not specified.
Is my understanding correct ?
On the other hand, I'm proposing the digital isolator instead of photocoupler.
Since the signal rate is not fast and photocoupler cheap, they don't use the digital isolator.
Please kindly advice for promoting the digital isolator instead of photocoupler.
Best Regards,
Ryuji Asaka
