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.
V DD operating range is 1.5V to 5.5V. Output is guaranteed to be asserted down to V DD = 1.2V.
V DD equals nominal “Typical Application (V DD )” as shown in “Standard Voltage Options Table.”
