output or control pins.

Hot Insertion

For Datacom and Telecom applications that have ten or more volts passing through the backplane, a high voltage from the power

supply may be seen at the device input pins during hot insertion. The PI3CHxx devices have maximum limits of 6V and 120mA for

20ns. If the power is higher or applied for a longer time or repeatedly reaches the maximum limits, the devices can be damaged.
