Note 2: All units are production tested at TA = +25NC. Specifications over temperature are guaranteed by design.
Note 3: Currents entering the IC are positive and currents exiting the IC are negative.
Note 4: When V18 is powered by an external voltage supply, it must have current capability above or equal to I18.
Note 5: Guaranteed by design; not production tested.
Note 6: CB is the total capacitance of either the clock or data line of the synchronous bus in pF.
