Description
The V 6108 is a CMOS integrated circuit that drives LCD.
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.
