RIO Isolation resistance Input to output, VIO = 500 V, all pins on each side of the barrier tied together creating a two-pin device,
TA = 25°C
>1012
Input to output, VIO = 500 V, 100°C ≤TA ≤TA max >1011
CIO Barrier capacitance VI = 0.4 sin (4E6πt) 1.9 pF
CI Input capacitance to ground VI = 0.4 sin (4E6πt) 1.3 pF
Creepage and clearance requirements should be applied according to the specific equipment isolation standards of an application. Care should be taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the isolator on the printed-circuit-board do not reduce this distance.
Creepage and clearance on a printed-circuit-board become equal according to the measurement techniques shown in the Isolation Glossary. Techniques such as inserting grooves and/or ribs on a printed-circuit-board are used to help increase these specifications.

Safety limiting intends to prevent potential damage to the isolation barrier upon failure of input or output circuitry. A failure 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.

The safety-limiting constraint is the absolute maximum junction temperature specified in the absolute maximum ratings table. The power dissipation and junction-to-air thermal impedance of the device installed in the application hardware determines the junction temperature. The assured junction-to-air thermal resistance in Thermal Information 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.
