4. The Fall time is highly dependent on the load conditions, i.e. load current for a specified value of COUT.
5. Static Crosstalk is a DC shift caused by switching ON one of the outputs through independent enable to all other outputs. This parameter
is highly dependent on overall PCB layout and requires the implementation of low–noise GROUND rules (e.g. Ground plane).
6. Dynamic crosstalk is the ratio between a forced output signal to signal transferred to other outputs. This requires special device
configuration to be measured.
