1. Input timing assumes an input slew rate of 1 ns (10% - 90%) and uses TTL / Automotive voltage thresholds.
2. All timing values for output signals in this table, are measured to 50% of the output voltage. All output timing is worst case
and includes the mismatching of rise and fall times of the output pads.
