NOTES:
1. The maximum total current, IOH(max) and IOL(max), for all outputs combined, should not exceed ±6 mA to satisfy the maximum
specified voltage drop.
2. The maximum total current, IOH(max) and IOL(max), for all outputs combined, should not exceed ±24 mA to satisfy the maximum
specified voltage drop.
