Notes: \n\n1) Schmitt trigger is a CMOS 74HC part. Do not use a\n bipolar 7414/74LS14 for the schmitt trigger. \n\n2) A 74HCT14 or CD40106 may be substituted for 74HC14.\n If so, some resistor/capacitor values may\n need to be adjusted.\n\n3) ~RESET~ time delay is determined by R14 and C18\n\n4) ~RESET~ pulse duration is determined by R17 and C20.\n\n5) SHIFTLOCK debounce time is determined by R12 and C17.
