V6108
40 Segment Static LCD Driver
Description
This V6108 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 latches under control of the strobe pin. The latched
data determines which segments are ON or OFF. Any
segments output can be used to drive a backplane. A
blank function is provided to clear the display.
