ON SEMICONDUCTOR MC14543BCPG 芯片, 4000系列 CMOS逻辑器件
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. 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.
