ELECTRICAL CHARACTERISTICS—V
DD1
= 3.3 V, V
DD2
= 2.5 V OPERATION
All typical specifications are at T
A
= 25°C, V
DD1
= 3.3 V, and V
DD2
= 2.5 V. Minimum and maximum specifications apply over the entire
recommended operation range of 3.0 V ≤ V
DD1
≤ 3.6 V, 2.25 V ≤ V
DD2
≤ 2.75 V, and −40°C ≤ T
A
≤ +125°C, unless otherwise noted.
Switching specifications are tested with C
L
= 15 pF and CMOS signal levels, unless otherwise noted.
For dc specifications and ac specifications, see Table 3 for parameters related to Side 1 operation, and see Table 6 for parameters related to
Side 2 operation.
