Where to buy ICs
Where is the best place to buy ic’s for the switch. They seem really expensive on eBay.
most commonly when buying IC's I prefer mouser, Digikey, and arrow. if I can't find them there than ill go to eBay, and if all else fails I can try Alibaba, but beware of buying Alibaba stuff, sometimes you can get "off-brand" chips, which are cheaper knockoffs of popular chips.
