Overview
The CD4017BPW, produced by Texas Instruments, is a CMOS Decade Counter integrated circuit. Although this specific package (TSSOP) is now obsolete and no longer manufactured, the CD4017 series remains widely used in various electronic circuits. This IC is known for its versatility in counting applications, particularly in low-range counting scenarios. It operates as a decade counter, capable of counting from 0 to 9, and then looping back to 0 on the subsequent clock pulse.
