MOTOROLA SEMICONDUCTOR TECHNICAL DATA LCD Segment / Common Driver with Controller CMOS MC141803 is a CMOS LCD Driver which consists of 4 annunciator outputs and 153 high voltage LCD driving signals (33 commons and 120 segments). MC141803 is split common output design. It has parallel interface capability for operating with general MCU. Besides the general LCD driver features, it has an on chip LCD bias Voltage Generator circuit such that fewer external components are required during application.
