Applications Information

Logic Inputs

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

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

Power Supply-Sequencing

Proper power supply sequencing is recommended for all CMOS devices. Always apply VCC before applying signals to the input/

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 PI3Vxxx 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.
