NOTES:
1. ALL RESISTORS ARE IN OHMS, 1% TOLERANCE, 1/8 W, UNLESS OTHERWISE SPECIFIED. BOM TAKES PRIORITY OVER SCHEMATIC
2. ASSOCIATE ONE DECOUPLING CAPACITOR PER EACH I.C. ON THE POWER TABLE.
3. REFER TO TABLE FOR VCC AND GND CONNECTIONS TO I.C.'S.
UNUSED GATES:
(SOME PARTS MAY BE TIGHTER TOLERANCE TO SIMPLIFY BOM).
