CD4520 Dual Binary Up Counter DIP-16 (CD4520 DIP IC)
The CD4520 is a high-voltage CMOS integrated circuit consisting of two identical, independent 4-bit binary synchronous up counters. Each counter is constructed with four flip-flops and internal gating for synchronous operation, allowing for precise binary counting from 0 to 15.
This IC is primarily used in digital frequency synthesizers, programmable timers, and multi-stage binary counting applications. It is a popular choice for Arduino electronics projects in India that require dual independent counting stages in a single package for clock division or event tracking.
