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.

FUNCTION DESCRIPTION
POWER SUPPLY
The power supplied to the PT2328 only needs single 5V, maximum workable voltage is 7V. In
theoretical the chip itself does not consume the current. Minimum supply voltage not less than 5V for
ensure low on-resistance of switch to keep the signal transmission quality.
ON/OFF SWITCH
PT2328 including 4 groups two way input/output multiplexer, please refer to the following truth table. In
5V supply voltage please maintain the input signal amplitude not greater than 2V for better signal
transmission quality.
