PERICOM PI3V312Q

PI3V312
Low On-Resistance, 3.3V High-Bandwidth
4-Port, 2:1 Mux/DeMux VideoSwitch
Features
Description
• Near-Zero propagation delay
Pericom Semiconductor’s PI3V312 is a 4-port, 2:1 Multiplexer/
Demultiplexer with 3-state outputs. The switch introduces no additional ground bounce noise or propagation delay.
• 5Ω switches connect inputs to outputs
• High signal passing bandwidth (500MHz)
• Beyond Rail-to-Rail switching
• 5V I/O tolerant with 3.3V supply
• 2.5V and 3.3V supply voltage operation
• Hot insertion capable
Low On-Resistance and High bandwidth make it ideal for video
and other applications. Also this device has exceptionally low
crosstalk and off-isolation, which is far greater than most analog
switches offered today. A single 3.3V supply is all that is required
for operation.

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 0.30ns 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 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 PI3V312 device 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.
