† 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 voltage values are with respect to the GND terminals.

2. Applies for external input and bidirectional buffers without hysteresis. VI > VCC does not apply to fail-safe terminals. Use V > VCC(5V)

for 5-V tolerant terminals.

3. Applies for external output and bidirectional buffers. VO > VCC does not apply to fail-safe terminals. Use VO >VCC(5V)for 5-Vtolerant

terminals.
