V SEL is a nonstandard input that has a logic threshold of approximately 0.9 V.
RC OUT is a nonstandard output intended to interface with other iso Power parts. It is not recommended for standard digital loads.
|CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining V O > 0.7 × V DD1 or 0.7 × V ISO for a high output or V O < 0.3 × V DD1 or 0.3 × V ISO for a
low output. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges.
