R RenatoBR New Member Jun 23, 2009 #1 Hi all, Is there Ic's that do the job? I need one to substitute the old uPC1701C from Nec that has the datasheet in Japanese. FAQ about uPC1701C: **broken link removed** The IC will be used to turn on/off a triac and is important not to have RF. Rgds Renato

K KMoffett Well-Known Member Jun 23, 2009 #2 Are you looking for phase control for dimming, or just on-off. If on-off, something like this will work: https://www.fairchildsemi.com/ds/MO/MOC3163-M.pdf But that's without knowing how your using it. Ken Last edited: Jun 23, 2009
