Description
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 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 PI3V314 offers a high-performance (375 MHz),
low-cost solution to switch between video sources.
