Enable/disable times are dominated by the RC time constant on the EN pin since the
transistor turn off is on the order of ns, but the enable RC is on the order of ms.
Fall time is dominated by the external pull-down driver with only a slight R
Rise time is dominated by the R
Skew time within the part is virtually non-existent, dominated by the difference in bond
wire lengths, which is typically small compared to the board-level routing differences.
Maximum data rate is dominated by the system capacitance and pull-up resistors.
