Notes
1. To avoid damages and wrong operation it is necessary to keep all 8.5 V supply voltages at a higher level than any 5 V supply voltage. This is also necessary during power-on and power-down sequences. Precautions have to be provided in such a way that interferences can not pull down the 8.5 V supply below the 5 V supply.
2. Machine model (R = 0 , C = 200 pF).
3. Human body model (R = 1.5 kW, C = 100 pF).
