LiquidtaCSryhseteatl4DUi.scpolamy ControllerThe IN472 Liquid Crystal Display (LDC) Controller is a perpheral
amember of the COPSTM family, fabricated using CMOS technology. The
.DIN472 drives a multiplexed liquid crystal directly. Data is loaded serially
and is held in internal latches. The IN472 contains an on-chip oscillator and
wgenerates all the multi-level waveforms for back-planes and segment
woutputs on a triplex display. One IN472 can drive 36 segments multiplexed
w as 3 x 12 (41/2 digit display). Two IN472 devices can be used together to
