Abstract
A binary to unary decoder for a video digital to analog converter is cascadeable in both a horizontal and a vertical direction. Video data is transmitted from a video data source and received by a plurality of unary decoders which convert the video data to a corresponding number of unary digits having comparable value. The unary decoders are arranged in a number of cascaded levels. A plurality of cascaded unary block drivers receive the unary digits and transit unary output digits to a video data bus. The plurality of unary block drivers are arranged in a number of tiers having a predetermined number of individual unary block drivers. The predetermined number of cascaded unary block drivers are enabled based upon the numerical value of the video data.
