Abstract : A high speed digital to analog converter circuit for converting a plurality of data bytes to corresponding analog signals at very high conversion rates. A computer image generator provides in response to each clock pulse of a first clock signal a set of eight data bytes. Each set of data bytes are then latched alternatively in first storage means or second storage means. Multiplexing means alternatively samples each set of data bytes latched in said first and second storage means, and an octet of digital to analog converters then converts each set of data bytes to a corresponding set of eight analog signals. Gating means, in turn, sequentially passes each set of analog signals so as to form at its output a video information signal which may be utilized to activate an image display apparatus.
