Description
The HI2304 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 3.3V power supply and pixel clock
input can be controlled individually, or connected together
as one. The HI2304 also has BLANK video control signal.
For faster speed and 5.0V operation, refer to the HI1178.
