AC ELECTRICAL CHARACTERISTICS (continued)
(V
A
= +2.35V to +3.6V, V
L
= +1.71V to +3.6V, V
EXT
= +1.71V to +3.6V, T
A
= -40NC to +85NC, unless otherwise noted. Typical values
are at V
A
= +2.8V, V
L
= +1.8V, V
EXT
= +2.5V, T
A
= +25NC.) (Notes 2, 3)
Note 2: All devices are production tested at T
A
= +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 V
18
is powered by an external voltage regulator, the external power supply must have current capability above or
equal to I
18
.
Note 5: Not production tested. Guaranteed by design.
Note 6: C
b
is the total capacitance of either the clock or data line of the synchronous bus in pF.
