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