Description
The HD66206 is an 80-channel LCD driver, which is used for liquid crystal dot matrix display. This
product can drive various types of liquid crystal displays, from small-sized to monochrome VGA-sized
displays. Since this product can function as a column and a common driver, an LCD panel can be
configured only with this product.
