TM ICM7231, ICM7232 Numeric/Alphanumeric Triplexed LCD Display Drivers Description The ICM7231 and ICM7232 family of integrated circuits are designed to generate the voltage levels and switching waveforms required to drive triplexed liquid-crystal displays. These chips also include input buffer and digit address decoding circuitry allowing six bits of input data to be decoded into 64 independent combinations of the output segments of the selected digit. The family is designed to interface to modern highperformance microprocessors and microcomputers and ease system requirements for ROM space and CPU time needed to service a display.
