From: billgull on 1 Dec 2008 21:28 does anyone have an especially good source for datasheets and or pin outs for old ic's. i have obtained a naked 40 pin dip chic for a digital clock and can't do much but look at it without a spec sheet. it's a 'mm5396n' manufactured by national semiconductor.

National Semiconductor MOS/LSI databook. I can scan and send to your email if you like.

(no pun intended, really) I probably built a clock with that chip or a close relative, back in the day. You might also try over at Jameco; they likely carried it once upon a time, either the bare chip or as part of a Jim-pak clock kit. The back of a rather yellowed AY-5-2376 (1980 date code on the chip) Jim-pak package shows an MM5262 and MM5314N. It won't be in their current inventory but you might get lucky with a call to customer support. -- Rich Webb Norfolk, VA
