The New Hotness

Over the years I’ve accumulated a bunch of obsolete ICs; all I can say is they weren’t obsolete at the time. Sometimes I need one, so here’s a list of the jelly-bean collection where I can find & update it as parts emerge from their hidey-holes in the Heap.

All hulking through-hole

• 138 1-to-8 demux
• 221 monstable (!)
• 139 1-to-4 decoder
