Applications Information

Logic Inputs

The logic control inputs can be driven up to 3.6V regardless of the supply voltage. For example, given a +3.3V supply, EN

may be driven LOW to 0V and HIGH to 3.6V. Driving EN Rail-to-Rail® minimizes power consumption.

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 PI3CH3345 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.
