PI3V724ZLE

Analog Switches - Special Purpose Overview

The PI3V724ZLE is a 7-channel video multiplexer/demultiplexer designed for switching between multiple VGA sources or endpoints. It supports full VGA signal paths including R, G, B, Hsync, Vsync, DDC data, and DDC clock channels. The device features an integrated monitor detection circuit that generates a hot plug output signal to inform the system of monitor connection status. It operates with dual power supplies of 3.3V and 5V and includes an integrated DDC level shifter. Key electrical parameters include a typical -3dB bandwidth of 1.7GHz, typical crosstalk of -38dB, and on-state resistance (Ron) of 4 Ohms. ESD tolerance reaches +/-4kV contact per IEC61000-4-2.

Analog Switches - Special Purpose Feature Summary
