The safety-limiting constraint is the maximum junction temperature specified in the data sheet. 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.

7.8 Safety Limiting Values

Safety limiting

of the I/O can 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.
