Note: Maximum ratings are absolute ratings; exceeding any one of these values may

cause irreversible damage to the integrated circuit. Integrated protection functions

are designed to prevent IC destruction under fault conditions. Fault conditions are

considered as outside normal operating range. Protections functions are not

designed for continuous repetitive operation.
