HI1178 General 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. Refer to the HI2304 for 3.3V operation.
