Data Sheet
ELECTRICAL CHARACTERISTICS—MIXED 3.3 V/5 V OPERATION
All voltages are relative to their respective ground. 3.0 V ≤ VDD1 ≤ 3.6 V, 4.5 V ≤ VDD2 ≤ 5.5 V. All minimum/maximum specifications
apply over the entire recommended operation range, −40°C ≤ TA ≤ 125°C, unless otherwise noted. All typical specifications are at TA =
25°C, VDD1 = 3.3 V, VDD2 = 5 V.

1 IOx is the Channel x output current, where x = A or B, VIxH is the input side logic high, and VIxL is the input side logic low.
2 |CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDDx. The common-mode voltage slew rates apply to both
rising and falling common-mode voltage edges.
