Data Sheet
ELECTRICAL CHARACTERISTICS—3.3 V 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 of 3.0 V ≤ V DD1 ≤ 3.6 V, 3.0 V ≤ V DD2 ≤ 3.6 V; and ?40°C ≤ T A ≤ +105°C, unless otherwise noted. Switching specifications
are tested with C L = 15 pF and CMOS signal levels, unless otherwise noted.

t PSK is the magnitude of the worst-case difference in t PHL or t PLH that is measured between units at the same operating temperature, supply voltages, and output load
within the recommended operating conditions.

|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.
