(1) The maximum total current, IOH(max) and IOL(max), for all outputs combined, should not exceed ±12 mA to hold the maximum voltage drop
specified.
(2) The maximum total current, IOH(max) and IOL(max), for all outputs combined, should not exceed ±48 mA to hold the maximum voltage drop
specified.

(1) Alternatively, a resistive divider with two 0.5-kΩ resistors 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.
