2-Port NanoSwitch™
Features
Description
• Near-Zero propagation delay
The PI3CH800 is a low voltage, 8-channel switch designed with a
fast enable. The switch creates no additional propagational delay
or additional ground bounce noise.

• High signal passing bandwidth (500 MHz)
• Beyond Rail-to-Rail switching
• 5V I/O Tolerant with 3.3V supply in OFF and ON state
• 2.5V and 3.3V supply voltage operation
• Hot insertion capable
The PI3CH800 device has an active LOW enable. It is very useful
in switching signals that have high bandwidth (500 MHz).
Applications
• High Bandwidth Data Switching
• Industrial operating temperature: –40ºC to +85ºC
• 2kV ESD protection (human body model)
• Latch-up performance: >250mA per JESD17
• Hot-Docking
• Analog Signal Switching
• Differential Signal Switching
• Packaging (Pb-free & Green available):
– 20-pin 150-mil wide plastic QSOP (Q)
– 20-pin 173-mil wide plastic TSSOP (L)

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 0.30ns 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 may be
®
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 V before applying signals to the input/
CC
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.
