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.

1) Exposure to these absolute maximum ratings for extended periods (t > 10 s) may affect device reliability.
2) External resistor required to keep current below absolute maximum rating when voltages ≥ 5.5 V are applied.
