CD4026 Decade Counters/Dividers
Package PDIP-16, SO-16, TSSOP-16 Series CD4000 (CMOS) Status Active (14-Aug-2021)
CD4026 overview
CD4026 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4026 has Decade Counters/Dividers
CD4026 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.
