No, 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. |

Anyway, just tie the output of 21 emitter followers together, add a resistor and - tadaaa - 21 input OR!
