LCD Segment / Common Driver CMOS

MC141531 is a CMOS LCD Driver which consists of 3 annunciator outputs and 137 high voltage LCD driving signals (17 common and 120 segment). 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.
