SPECIFICATIONS

All voltages are relative to their respective grounds; 4.5 V ≤ VCC ≤ 5.5 V; 3.0 V ≤ VIO ≤ 5.5 V. All minimum/maximum specifications apply

over the entire recommended operation range, unless otherwise noted. All typical specifications are at TA = 25°C, VCC = 5 V, and VIO = 5 V

unless otherwise noted.

CM is the maximum common-mode voltage slew rate that can be sustained while maintaining specification compliant operation. VCM is the common-mode potential

difference between the logic and bus sides. The transient magnitude is the range over which the common mode is slewed. The common-mode voltage slew rates

apply to both rising and falling common-mode voltage edges.
