I just got a butload of IC's from Purdue Salvage, and was wondering if anyone could help me identify a few of the ones I couldn't google a description of. T5650, T5670, T5681. Company logo on chip looks like an X with a P on it, or an italic P with a \ through it to make an X with its stem. All approx 18-pins and DIP (could be 16). 353BN 8-pin DIP National Semiconductor IC L1A3220 44-pin QFP surface mount IC triangle (upside-down delta) logo L3036FN-C 44-pin QFP "ST" logo N8T125 20-pin DIP "SA" logo OMA110 6-pin (optocoupler?) OP27FP 8-pin (OpAmp?) Also if you could point me to a source for data on any of the above, I'd be very greatful. -- Pat
