CD4543 BCD to 7-Segment Decoder
Series CD4000 (CMOS)
CD4543 overview
CD4543 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4543 has BCD to 7-Segment Decoder
CD4543 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
