Absolute Maximum Ratings
Absolute maximum ratings are those values beyond which damage to the device may occur. Functional
operation under these conditions or at any other condition beyond those indicated in the operational
sections of this specification is not implied:

where N is the number of connected cards. Requiring the sum of the host and bus capacitance’s not to
exceed 30 pF for up to 10 cards, and 40 pF for up to 30 cards, the following values must not be exceeded:
