Notes:
1.
Measured with a test load of 20 pF connected to V SSQ .
2.
Output slew rate for rising edge is measured between VILD(DC) to VIHD(AC) and for falling edge between VIHD(DC) to VILD(AC).
3.
The ratio of pull-up slew rate to pull-down slew rate is specified for the same temperature and voltage, over the entire temperature and
voltage range. For a given output, it re
presents the maximum difference between pull-up and pull-down drivers due to process variation.
