8-Digit, Multiplexed, LED Decoder Driver

The Maxim ICM7218 display driver interfaces microprocessors to an 8 digit, 7 segment, numeric LED display. Included on chip are two types of 7 segment decoders, multiplex scan circuitry, segment and digit drivers, and an 8 x 8 static memory.

The ICM7218A and ICM7218B accept data in a serial format and drive common anode (ICM7218A) or common cathode (ICM72188) displays. The ICM7218C and ICM7218D accept data in a parallel format and drive common anode (ICM7218C) or common cathode (ICM7218D) displays. All four versions can display the data in either hexadecimal or code B format. The ICM7218A and ICM72188 also feature a No Decode mode where each individual segment can be independently controlled. This is particularly useful in driving bar graphs.

The Maxim ICM7218 is an alternative for both the lntersil ICM7218 and ICM7228. When ordering, specify ICM7218 for both devices.
