AC ELECTRICAL CHARACTERISTICS (continued)
(VA = +2.35V to +3.6V, VL = +1.71V to +3.6V, VEXT = +1.71V to +3.6V, TA = -40NC to +85NC, unless otherwise noted. Typical values
are at VA = +2.8V, VL = +1.8V, VEXT = +2.5V, TA = +25NC.) (Notes 2, 3)
Note 2: All devices are production tested at TA = +25NC. Specifications over temperature are guaranteed by design.
Note 3: Currents entering the IC are negative, and currents exiting the IC are positive.
Note 4: When V18 is powered by an external voltage regulator, the external power supply must have current capability above or
equal to I18.
Note 5: Not production tested. Guaranteed by design.
Note 6: Cb is the total capacitance of either the clock or data line of the synchronous bus in pF.
