PT2328 V1.3

- 4 -

August, 2005

Low On-Resistance Wideband/Video Quad 2-Channel Mux/DeMux

PT2328

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.
