Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Specification for packaged product only.
V IL(MAX) = Maximum positive voltage applied to the input which will be accepted by the device as a logic low.
V IH(MIN) = Minimum positive voltage applied to the input which will be accepted by the device as a logic high.
