Note 1. Exceeding the absolute maximum rating may damage the device.
Note 2. The device is not guaranteed to function outside its operating rating.
Note 3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 100pF in series with 1.5k .
Note 4.
Note 5.
V_DD operating range is 1.5V to 5.5V. Output is guaranteed to be held low down to V_DD = 1.2V.
