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 mostanalog switches offered today, only need a single 5V supply for operation. The PT2328 is a good choice toreplacing the “switches + buffer amplifier” solution in both cost and performance reasons.
