The MC44002/7 is a highly advanced circuit which performs most of the

basic functions required for a color TV. All of its advanced features are under

processor control via an I2C bus, enabling potentiometer controls to be

removed completely. In this way the component count may be reduced

dramatically, allowing significant cost savings together with the possibility of

implementing sophisticated automatic test routines. Using the MC44002/7,

TV manufacturers will be able to build a standard chassis for anywhere in the

world. Additional features include 4 selectable matrix modes (primarily for

NTSC), fast beam current limiting and 16:9 display.
