Video Multiplexer GX434


Posted on Dec 8, 2012

The GX434 is a high performance low cost monolithic 4x1 video multiplexer incorporating four bipolar switches with a common output, a 2 to 4 address decoder and fast chip select circuitry. The chip select input allows for multi-chip paralleled operation in routing matrix applications. The chip is selected by applying a logic 0 on the chip select input.



The results are averaged to reduce the standard deviation and therefore improve the accuracy of the measurement. The output from the device under test is AC coupled to a buffer amplifier which allows the buffer to operate at a constant luminance level
