I decided to restart a project that has been languishing for a couple of months now and get started on the KISS-68030. This is a seriously cool design and I'm pretty excited to get going. Right off the bat, I started to check on availability on all of those 74FxxxA parts and discovered that I might have better luck looking unicorns. Almost none of these are stocked by my usual sources: Jameco/Mouser/Digikey. A few, but not all, of them can be found on ebay but that's not my favorite source. So, where are other people finding these?

The hardest part to find for the KISS-68030 is the 74F133. There are listings on eBay, and a good bit of price gouging. This is a $1 - $1.50 part. Don't pay more.

UTSource, very active on eBay until the recent Trump trade fuss, is a very reliable supplier in China (

Note: the KISS address multiplexor may be any of 74F157/158/257/258.

I was also going to suggest Unicorn Electronics, but they seem to have discontinued their lines of 74?xx IC's.
