This document describes the features and characteristics of MM5452 and MM5453 liquid crystal display drivers, including CMOS metal gate low threshold enhancement mode devices, driving up to 32 segments of LCD, and cascaded operation capability.
The MM5452 and MM5453 are monolithic CMOS LCD driver ICs that can drive up to 32 or 33 segments and support cascaded operation. They accept serial data and clock inputs, require no load signal, and are compatible with TTL logic levels.
The document details absolute maximum ratings, electrical characteristics, connection diagrams, and typical application circuits. It also includes physical dimensions, package information, and a life‑support policy disclaimer.
