SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = VDD2 = 5 V. Minimum/maximum specifications apply over the entire recommended
operation range of 4.5 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 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.
