ICM7212AIQH+TD

The Maxim ICM7211 (LCD) and ICM7212AIQH+TD (LED) four digit, seven segment display drivers include input data latches, BCD to segment decoders, and all level translation and timing circuits needed to drive non-mulitplexed displays. Both the ICM7211 and ICM7212AIQH+TD are available in two data input configurations: a mulitplexed BCD interface version and a microprocessor interface version. The multiplexed BCD interface version has four BCD data inputs and four separate digit strobes. The microprocessor interface versions, designated by an "M" suffix, have four chip selects or WRITE inputs. The ICM7211 and ICM7212AIQH+TD decode the BCD data via an onboard character font ROM. There are two different character fonts available, hexadecimal and Code B.
