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.
