PI3CH480

Low Voltage, High-Bandwidth, 4-Channel

2:1 Mux/Demux, NanoSwitch™

Applications Information

Logic Inputs

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

Power Supply-Sequencing

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.
