Low On-Resistance Wideband/Video Quad 2-Channel Mux/DeMux
PT2328
DESCRIPTION
The PT2328 is a true bidirectional Quad 2-channel multiplexer/ de-multiplexer utilizing CMOS
Technology. It is recommended for both RGB and composite video switching applications. The video
switch can be driven from a video DAC or a composite video source.
The very low ON-resistance and wide bandwidth make it ideal for video and other applications.
High output current which is far greater than most analog switches offered today, only need a single 5V
supply for operation. The PT2328 is a good choice to replacing the “switches + buffer amplifier”
solution in both cost and performance reasons.
