The circuit drives up to 40 LCD segments from a serial clocked input. It has a serial output for cascading to further drives. The serially clocked data is parallel loaded into 40 latches under control of the strobe pin. The latched data determines which segments are ON or OFF. Any segment output can be used to drive a backplane. A blank function is provided to clear the display.
