1) 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.
2) not subject to production test, specified by design
3) If channels are connected in parallel, output clamp is usually accomplished by the channel with the lowest V_ON(CL)
4) Higher operating temperature at normal function for each channel available
