Description
The PI3V341 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. 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 PI3V341 offers a high-performance (375 MHz), low-cost solution to switch between video sources. The PI3V341/-A is an enhanced solution w/ enhanced ESD protection support, up to 8kV contact.

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.

PI3V341/PI3V341-A Low On-Resistance, 3.3V High-Bandwidth 3-Port, 4:1 Mux/DeMux Video Switch 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(R) minimizes power consumption.
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.
