CMOS IC Dot-Matrix LCD Drivers

Overview The LC7940KD and LC7941KDR are segment driver LSIs for driving large, dot-matrix LCD displays. They read 4-bit parallel or serial input, display data from a controller into an 80-bit latch, and then generate LCD drive signals corresponding to that data. The LC7940KD and LC7941KDR feature
