Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltages are with respect to ground unless otherwise specified.
2. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
3. VI and VO are used to denote specific conditions for VI/O.
4. II and IO are used to denote specific conditions for II/O.
5. The package thermal impedance is calculated in accordance with JESD 51-7.

NOTES:
6. All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application
report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
7. In applications with fast edge rates, multiple outputs switching, and operating at high frequencies, the output may have little or no
level-shifting effect.
