Abstract: A digital/analog conversion apparatus with a color palette RAM for a multimedia, comprising a first latch circuit for inputting a pixel address signal, a pixel mask register for selectively masking the pixel address signal from the first latch circuit in response to a control signal from a microprocessor interface circuit, a second latch circuit for storing digital color information temporarily, and first to third digital/analog converters for converting the digital color information from the second latch circuit into analog R, G and B color information. The palette RAM stores digital color information from the microprocessor interface circuit and outputs the digital color information stored in its location corresponding to the pixel address signal from the pixel mask register to the second latch circuit.

Abstract: A digital/analog converter circuit comprising first to third transistors, the first transistor having a gate terminal for inputting a constant voltage and one side terminal for inputting a power source voltage, the second transistor having a gate terminal for inputting a first digital signal, one side terminal connected to the other side terminal of the first transistor and the other side terminal forming a first output terminal, the third transistor having a gate terminal for inputting a second digital signal of the opposite phase to that of the first digital signal, one side terminal connected to the other side terminal of the first transistor and the other side terminal forming a second output terminal. A buffer part buffers a digital input signal to provide the second digital signal. An inverter part inverts the digital input signal to provide the first digital signal.
