PI3V514
Low On-Resistance, 3.3V High-Bandwidth
5-port, 4:1 Mux/DeMux VideoSwitch
Description
The PI3V514 is a true bi-directional 5-Port 4:1 multiplexer/
demultiplexer with Hi-Z outputs that is recommended for both RGB
and composite video switching applications. With the additional 2
ports, vertical and horizontal synchronous signals can be switched
in addition to switching the RGB and composite signals between
different components, such as DVD, VCR, PCs and etc. With the
increased 4:1 channels, multiple components, such as VCR, DVD,
PC1, PC2 and etc. can be put on the video networks. The Video
switch 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 bidirectional 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 PI3V514 offers a high-performance (400 MHz),
low-cost solution to switch between video sources.
Applications
• Projection TV and LCD TV
• Video consumer applications
• Analog video signal processing

Notes:
1. For video applications: In order to control Muxing and DeMuxing
of all the 20 to 5 channels with the same control plane, the follow-
ing connectoins need to be made on the board:
a. EN1, EN2 and EN3 need to be tied together
b. S1, S3 and S5 need to be tied together
c. S0, S2, and S4 need to be tied together
