CD4029 Binary-Decade Up-Down Counter
Series CD4000 (CMOS)
CD4029 overview
CD4029 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4029 has Binary-Decade Up-Down Counter
CD4029 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.
