CMOS 4-bit synchronous binary counter

The CD4520 DIP Dual 4-Bit Synchronous Binary Counter is a CMOS IC that provides two independent 4-bit synchronous binary counters capable of counting from 0 to 15. It features clear (CLR) and enable (EN) inputs for flexible control, and ripple carry outputs for cascading counters. With a wide operating voltage range (3V to 18V) and low power consumption, the CD4520 is ideal for frequency counting, digital timekeeping, and event monitoring in embedded systems and control applications. The IC is packaged in a DIP-16 format for easy integration into breadboards and PCBs.
