1、 SEMICONDUCTOR TECHNICAL DATA ! # ! ! # " $ ! The MC14543B BCDtoseven segment latch/decoder/driver is designedfor use with liquid crystalouts, and is constructed with complementaryMOS (CMOS) enhancement mode devices. The circuit provides the functions of a 4bit storage latch and an 8421 BCDtose

2、ven segment decoder and driver. The device has the capability to invert the logic levels ofthe output combination. The phase (Ph), blanking (BI), and latch disable (LD)inputs are used to reverse the ttable phase, blank the display, and storea BCD code, respectively. For liquid crystal (LC)outs, a sq
