on page 9, we can see two graph small and large signal pulse response.

is the dv/dt correct?

is the slew rate 4v/10us?

    The slew rate is better than that and is typically measured between 10% to 90%. Eyeballing the graph this looks better than 5us, which is in line with the slew rate spec of 1V/us.

    The output settling time to 1% final value, on the other hand, is specified as 20us typical. This may be what you are referring to. In the graphs the signal seems to settle around that value.
