LCD Segment / Common Driver with Controller
CMOS

MC141539 is a CMOS LCD Driver which consists of 4 annunciator outputs and 152 high voltage LCD driving signals (32 commons and 120 segments). It has parallel interface capability for operating with general MCU. Besides the general LCD driver features, it has on chip LCD bias voltage generator circuit such that fewer external components are required during application.
