Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. V_in and V_out should be constrained to the range GND ≤ (V_in or V_out) ≤ V_CC. Unused inputs must always be tied to an appropriate logic voltage
level (e.g., either GND or V_CC). Unused outputs must be left open.
2. Tested to EIA/JESD22--A114--A
3. Tested to EIA/JESD22--A115--A
4. Tested to JESD22--C101--A
5. Tested to EIA/JESD78
