Hello to everyone, I'm new and have heard good things about this site. I have been on a mission to find the any information at all, or even a pinout of a National Semiconductor Corp. DIP 14 pin chip that has LM1817N on the 25 IC's per slide rail and SL62064 underneath that. The chip itself has NS/744 5341-1 acrossed it. Currently I'm planning to use them as a poor mans logos cause I have just over 600 of them all in rails of 25 per. in a box from Nat. Semi Corp.who went out of business and sold a big part of the business off to TI Texas Instruments. I contacted TI and they have no record...
