Add IST, if IST > 0

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.

)

If channels are connected in parallel, output clamp is usually accomplished by the channel with the lowest
