Table 4. Absolute Maximum Ratings

The integrated circuit must not be destroyed by use at the limit values.

Each limit value can be used, as long as no other limit is violated.

Voltage reference point:

All values are, if not otherwise stated, relative to ground.

Direction of current flow:

Current flow into a pin is positive.

Rise-, fall- and delaytimes:

If not otherwise stated, all rise times are between 10% and 90%, fall times

between 90% and 10% and delay times at 50% of the relevant steps.
