3. The maximum total current, I_OHmax and I_OLmax, for all outputs combined, should not exceed ±12 mA to hold the maximum
voltage drop specified.
4. The maximum total current, I_OHmax and I_OLmax, for all outputs combined, should not exceed ±48 mA to hold the maximum
voltage drop specified.

NOTES: 1. Alternatively a resistive divider with 2 times 2 kW between V_CC and V_SS is used as load. The output is connected to the center tap
of the divider.
2. The output voltage reaches at least 10% and 90% V_CC at the specified toggle frequency.
