High quality video routing A/D input multiplexing Sample and hold circuits TV/ CATV/ monitor switching IN 0 GND IN 1 GND IN 2 CIRCUIT DESCRIPTION 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. Unlike devices using MOS bilateral switching elements, these bipolar circuits represent fully buffered, unilateral transmission paths when selected. This results in extremely high output to input isolation. They also feature fast make-before-break switching action. These features eliminate such problems as switching 'glitches' and output-to-input signal feedthrough. Th……
