7.8 Safety Limiting Values
Safety limiting intends to prevent potential damage to the isolation barrier upon failure of input or output (I/O) circuitry. A
failure of the I/O circuitry may allow low resistance to ground or the supply and, without current limiting, dissipate sufficient
power to overheat the die and damage the isolation barrier, potentially leading to secondary system failures.

(1) Input, output, or the sum of input and output power must not exceed this value.
The maximum safety temperature is the maximum junction temperature specified for the device. The power
dissipation and junction-to-air thermal impedance of the device installed in the application hardware determines
the junction temperature. The assumed junction-to-air thermal resistance in the Thermal Information table is that
of a device installed on a high-K test board for leaded surface-mount packages. The power is the recommended
maximum input voltage times the current. The junction temperature is then the ambient temperature plus the
power times the junction-to-air thermal resistance.
