CD4026 Decade Counter/Divider – 7 Segment Driver IC

CD4026 is a decade counter which consists of a 5-stage Johnson decade counter. It has an output decoder which converts the johnson output to 7-segment decoder output. It drives 1 stage (0-9) numeric count directly to a common cathode 7 segment display. Increasing the count as simple with CD4026 IC as by giving a high clock pulse. Displaying multiple digits is also possible by cascading more than 1 CD4026 IC. It comes in standard 16-pin PDIP.
