Note 1:

Specification for packaged product only.

“x” in front of a pin name refers to either A or B (e.g., xHI can be either AHI or BHI).

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.

xLI/xHI mode with inputs non-overlapping, assumes xHS low before xLI goes high and xLO low before xHI

goes high.

PWM mode (MIC4606-2) or LI/HI mode (MIC4606-1) with overlapping xLI/xHI inputs.
