†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. Applies for external input and bidirectional buffers. VI > VCC does not apply to fail-safe terminals. PCI terminals and miscellaneous
terminals are measured with respect to VCCP instead of VCC. PC Card terminals are measured with respect to CardBus VCC. The
limit specified applies for a dc condition.
2. Applies for external output and bidirectional buffers. VO > VCC does not apply to fail-safe terminals. PCI terminals and miscellaneous
terminals are measured with respect to VCCP instead of VCC. PC Card terminals are measured with respect to CardBus VCC. The
limit specified applies for a dc condition.
