1) Not subject to production test, specified by design.

2) Exposure to those absolute maximum ratings for extended periods of time (t > 10s) may affect device reliability

3) ESD susceptibility HBM according to EIA/JESD 22-A 114B (1.5kΩ,100pF).

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.
