1) Not subject to production test, specified by design.
2) For transient durations of tTR < 1s.
3) ESD susceptibility, HBM according to ANSI/ESDA/JEDEC JS-001 (1.5 k, 100 pF).
4) ESD susceptibility, Charged Device Model “CDM” ESDA STM5.3.1 or ANSI/ESD S.5.3.1.

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.
