ELECTRICAL CHARACTERISTICS—MIXED 5 V/3.3 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = 5 V, VDD2 = 3.3 V. Minimum/maximum specifications apply over the entire recom-
mended operation range of 4.5 V ≤ VDD1 ≤ 5.5 V, 3.0 V ≤ VDD2 ≤ 3.6 V; and −40°C ≤ TA ≤ +105°C, unless otherwise noted. Switching
specifications are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted.

1 tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages, and output load
within the recommended operating conditions.

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