Description
The ICM7231 and ICM7232 family of integrated circuits are
designed to generate the voltage levels and switching wave-
forms 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 high-
performance microprocessors and microcomputers and
ease system requirements for ROM space and CPU time
needed to service a display.
