Note 1: âxâ in front of a pin name refers to either A, B or C phase. (e.g. xHI can be either AHI, BHI or CHI).

2: Specification for packaged product only.

3: VIL(MAX) = maximum positive voltage applied to the input which will be accepted by the device as a logic

low.

VIH(MIN) = minimum positive voltage applied to the input which will be accepted by the device as a logic

high.

4: Guaranteed by design. Not production tested.
