alt Hacker NewsNo, it wasn't. Those are mostly available in PLCC and DIP packages and even if you can get the SOIC/TSSOP versions they still cost $1.20 each at 10k volume. That's flat-out unacceptable for 99% of the things I do. The entire rest of the board I was talking about was $4.60. Processor included. $1.20 is not going to fly.
“Reduces use case and requirements to something impossibly niche and low volume then yells at the clouds.”
Anyway, just tie the output of 21 emitter followers together, add a resistor and - tadaaa - 21 input OR!
