Notes:
1. Exceeding the absolute maximum ratings may damage the device.
2. The device is not guaranteed to function outside its operating ratings.
3. Devices are ESD sensitive. Handling precautions are recommended.
4. Specification for packaged product only.
5. 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.
