4 General Product Characteristics
4.1 Absolute Maximum Ratings
Note: Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.
4.2 Functional Range
Note: Within the functional or operating range, the IC operates as described in the circuit description. The electrical
characteristics are specified within the conditions given in the Electrical Characteristics table.
