CD4045 21-stage counter
Package PDIP-16 Series CD4000 (CMOS) Status Active (10-Dec-2020)
CD4045 overview
CD4045 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4045 has 21-stage counter
CD4045 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.
