NOTES: 1. 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.
2. 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 kΩ 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.
