Product Summary

The ICM7218CIQI is an 8 digit display driver. The Maxim ICM7218CIQI 8 digit, seven segment display drivers include input data latches, BCD to segment decoders, and all level translation and timing circuits needed to drive nonmultiplexed displays. The ICM7218CIQI is available in two data input configurations: a multiplexed BCD interface version and a microprocessor interface version. The multiplexed BCD interface version has four BCD data inputs and four separate digit strobes. The micro;processor interface versions, designated by an MM suffix, have four BCD data inputs, two digit address lines, and two chip selects or WRITE inputs. The ICM7218CIQI decodes the BCD data via an onboard character font ROM. There are two different character fonts available, hexadecimal and Code B.
