NOTES: 1. The maximum total current, I
OH(max)
and I
OL(max),
for all outputs combined, should not exceed ±12 mA to satisfy the maximum
specified voltage drop.
2. The maximum total current, I
OH(max)
and I
OL(max),
for all outputs combined, should not exceed ±24 mA to satisfy the maximum
specified voltage drop.
