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 range the IC operates as described in the circuit description. The electrical

characteristics are specified within the conditions given in the related electrical characteristics table.
