PERICOM PI3V314

PI3V314
Low On-Resistance, 3.3V High-Bandwidth
3-Port, 4:1 Mux/DeMux VideoSwitch
Features
Description
• Near-Zero propagation delay
The PI3V314 is a true bi-directional 3-Port 4:1 multiplexer/
demultiplexer with Hi-Z outputs that is recommended for both RGB
and composite video switching applications. With the increased 4:
1 channels, multiple components, such as VCR, DVD, PC1, PC2
and etc. can be put on the video networks. The VideoSwitch can
be driven from a current output RAMDAC or voltage output composite video source.
• 5Ω switches connect inputs to outputs
• High signal passing bandwidth (375MHz)
• 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 Crosstalk (XTALK = -60dB Typ.)
• Low Off-Isolation (OIRR = -60db Typ.)
• Industrial operating temperature: -40ºC to +85ºC
• 2KV ESD Protection (human body model)
• Latch-up performance >250mA per JESD17
• Packaging (Pb-free & greeen available):
– 40-Pin 150-mil wide plastic BQSOP(B)
Low On-Resistance, Low Crosstalk, Low OFF Isolation and wide
bandwidth features make it ideal for video and other applications.
Industry leading advantages include a near zero propagation delay,
resulting from its low channel resistance and I/O capacitance. The
switch is bi-directional and offers little or no attenuation of the highspeed signals at the outputs. The device also has exceptional high
current capability which is far greater than most analog switches
offered today. The PI3V314 offers a high-performance (375 MHz),
low-cost solution to switch between video sources.

4. Measured by the voltage drop between Y and In pin at indicated current through the switch. On-Resistance is determined
by the lower of the voltages on the two (Y, In) pins.
5. This parameter is determined by device characterization but is not production tested.

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 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.
