Note 1:

Specifications are for packaged product only.

2:

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.

3:

Not production tested.
