Supply voltages higher than Vbb(AZ) require an external current limit for the GND and status pins (a 150 Ω
resistor in the GND connection is recommended). See also V

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
