1. The maximum total current, IOHmax and IOLmax, for all outputs combined, should not exceed ±12 mA to hold the maximum
voltage drop specified.
2. The maximum total current, IOHmax and IOLmax, for all outputs combined, should not exceed ±48 mA to hold the maximum
voltage drop specified.

NOTES: 1. A resistive divider with 2 times 0.5 kW between VCC and VSS 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% VCC at the specified toggle frequency.
