a voltage difference of 3.6V, for up to 50 milliseconds at power-up and power-
down.Within 50 milliseconds of power-up the voltages must be within their respective
absolute voltage limits. At power-down, within 50 milliseconds of either voltage going
outside its operational range, the voltage difference should not exceed 3.6V and both
voltages must be returned below 0.1V:

Similar criteria also apply to power down in case of power failure situations:

Within the grey boxes any shape of V
limits of each signal are not exceeded, the slew rate recommendation for V
