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 com-

posite 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 high-

speed 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 protec-

tion support, up to 8kV contact.

Applications

• Projection TV and LCD TV

• Video consumer applications

• Analog video signal processing
