LCD7 段显示BCD

Overview

The MC14543BDG is a BCD-to-seven segment Latch/Decoder/Driver 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. The outputs of the circuit are connected directly to the segments of the LC readout. For other types of readouts, such as light-emitting diode (LED), incandescent, gas discharge and fluorescent readouts, connection diagrams are given on this data sheet.
