What´s the fastest/cheapest OPTOs ? I mean i´m using 4N25 optos. Cheap but not so fast: down to 22 kHz (if my brain is not wrong)
I know some optos are really fast and cheap too. Toshiba has a TLP521 (4 legs) opto. Is that good? heare in brazil it costs US$ 0.50, like 4N25.
Thanks guys , you are great! |
