DESCRIPTION/ORDERING INFORMATION
The TS3V712EL is a high bandwidth, 7-channel video demultiplexer for switching between a single VGA source
and one of two end points. The device is designed for ensuring video signal integrity and minimizing video signal
attenuation by providing high bandwidth of 1.3 GHz.
The TS3V712EL has integrated level shifting buffers for the HSYNC and VSYNC signals which provide voltage level
translation between 3.3 V and 5 V logic. The SCL and SDA lines use NMOS switches which clamp the output
voltage to 1 V below VDD.
The video signals are protected against ESD with integrated diodes to VDD and GND that support levels up to
±2-kV Contact Discharge (IEC61000-4-2) and 7-kV Human Body Model (JESD22-A114E).
