Description
The HI1178 is a triple 8-bit, high-speed, CMOS D/A converter designed for video band use. It has three separate, 8-bit, pixel inputs, one each for red, green, and blue video data. A single 5.0V power supply and pixel clock input is all that is required to make the device operational. A bias voltage generator is internal. Each channel clock input can be controlled individually, or connected together as one. The HI1178 also has BLANK video control signal.
