ELECTRICAL CHARACTERISTICS—3.3 V, 125°C OPERATION
All typical specifications are at T A = 25°C, V DD1 = V DD2 = 3.3 V. Minimum/maximum specifications apply over the entire recommended
operation range: 3.0 V ≤ V DD1 ≤ 3.6 V, 3.0 V ≤ V DD2 ≤ 3.6 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.

|CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining V O > 0.8 V DD . The common-mode voltage slew rates apply to both
rising and falling common-mode voltage edges.
