8-Digit LED Microprocessor-Compatible Multiplexed Display Decoder Driver

The ICM7218 series of universal LED Driver systems provide, in a single package, all the circuitry necessary to Interface most common Microprocessors or digital systems to an LED Display Included on chip are an 8-byte static Display memory, two types of 7-segment decoders, multiplex scan circuitry, and high current digit and segment drivers for either common-cathode or common-anode Displays
The lCM7218A and 1CM7218B feature two control lines (WRITE and MODE) which write either 4 bits of control information (DATA COMING, SHUTDOWN, DECODE, and HEXA/CODE B) or 8 bits of Display input data. Display data is automatically sequenced into the 8-byte internal memory on successive positive going WRITE pulses. Data may be displayed either directly or decoded in Hexadecimal or Code B formats.
The ICM7218C and lCM7218D feature two control lines (WRITE and HEXA/CODE B/SHUTDOWN), 4 separate Display data input lines, and 3 digit address lines. Display data is written into the internal memory by setting up a digit address and strobing the WRITE line low. Only Hexadecimal and Code B formats are available for Display outputs.
