1. Input slew rate is based on the lesser of the slew rates determined by either V
2. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device.

1. Input slew rate is based on the lesser of the slew rates determined by either V
2. Input slew rate is based on the larger of AC to AC delta rise, fall rate and DC to DC delta rise, fall rate.
3. The delta rise, fall rate is calculated as: [1/(slew rate 1)] - [1/(slew rate 2)]
4. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device.

transitions.
For example: slew rate 1 = 0.5 V/ns; slew rate 2 = 0.4 V/ns
Delta rise, fall = (1/0.5) - (1/0.4) [ns/V]
Using the table above, this would result in an increase in t
