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.
