optocoupler high frequency

[yassin.kraouch]

Hi,
who have an idea on how to isolate a a high frequency signal ?

or can you give me the link of an optocoupler with very small time response ?

PS9661 = OPTOCOUPLER 25 Mbps CMOS OUTPUT TYPE

6N137, VO2601, VO2611, VO2630, VO2631, VO4661 = 10MBd

What about TLP2531? It has a rise time of 0.2us, fall time of 0.3us.

Hope this helps.

Hello

I think that 6n137 opto is more fast
