2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between A and B pin at indicated current through the switch. On-Resistance is determined
by the lower of the voltages on the two (A,B) pins.

Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. The switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time
constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical
driving signals, it adds very little propagational delay to the system. Propagational delay of the switch when used in a system is determined by
the driving circuit on the driving side of the switch and its interaction with the load on the driven side.

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 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.
