PT2328 V1.3

- 1 -

August, 2005

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.
