Advance Information
LCD Segment / Common Driver
CMOS
MC141531 is a CMOS LCD Driver which consists of 3 annunciator out-
puts and 137 high voltage LCD driving signals (17 common and 120 seg-
ment). It has parallel interface capability for operating with general MCU.
Besides the general LCD driver features, it has on chip LCD bias voltage
generator circuits such that limited external component is required during
application.
