The LC7940YC and LC7941YC are segment driver ICs for driving large, dotmatrix LCD displays. They read 4bit parallel or serial input, display data from a controller into an 80bit latch, and then generate LCD drive signals corresponding to that data.
The LC7940YC and LC7941YC feature mirrorimage pin assignments, allowing them to be used together to increase
component density. They are designed to be used with the LC7942YC common driver to drive large LCD panels.
