Hey again everyone
Just a quick Q about opto-couplers. I need some for my modified sine wave generator but they will need to be able to handle high frequency switching. I've found a couple of Vishay ones that look fine @ 250kHz cut-off frequencies but..... the two I have found seem identical but they have different phototransistor configurations. Is this just a non-issue really and I just run opposite tracks? Apart from that they even have the same descriptions but different titles.
Here they are, can some please tell me which of these is the best? If one even is.

This is my first time using these components so some advice would be greatly appreciated.
Thanks guys
