LCD DRVR 8DIGIT 5V 40-Pin PDIP

The MAX7231 family of integrated circuits is a complete line of triplexed liquid crystal display (LCD) drivers. These devices interface microprocessors (or digital systems) to multiplexed numeric and alphanumeric displays. The MAX7231 drives 8 digits and accepts data in a parallel format. The devices feature two independent annunciators per digit. Each device includes an input buffer, digit address decoding circuitry and mask-programmed ROM allowing six bits of input data to be decoded into 64 independent combinations of the output segments of each digit. This off loads the microprocessor system, reducing the ROM space and CPU time needed to service a display.

• MAX7231 drives 8 digits/7 segments; parallel input format; 2 annunciators per digit
• On-chip oscillator
• Direct interface to microprocessors
