MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14543B BCD-to-Seven Segment Latch/Decoder/Driver for Liquid Crystals The MC14543B BCD–to–seven segment latch/decoder/driver is designed for use with liquid crystal readouts, and is constructed with complementary MOS (CMOS) enhancement mode devices. The circuit provides the functions of a 4–bit storage latch and an 8421 BCD–to–seven segment decoder and driver. The device has the capability to invert the logic levels of the output combination. The phase (Ph), blanking (BI), and latch disable (LD) inputs are used to reverse the truth table phase, blank the display, and store a BCD code, respectively. For liquid crystal (LC) readouts, a square wave is applied to the Ph input of the circuit and the electrically common backplane of the display.
