Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5kΩ in series with 100pF.
4. Specification for packaged product only.
5. The V_TT voltage accuracy is measured as a delta voltage from the reference output (V_TT - V_REF).
6. Shutdown current is measured only on the V_CC pin. The V_DDQ pin will always draw a minimum amount of current when voltage is applied.
