CD4516 Presettable Binary Up/Down Counter DIP-16 (CD4516 DIP IC)
The CD4516 is a high-voltage CMOS integrated circuit that functions as a 4-bit binary synchronous up/down counter. It is designed with internal look-ahead carry logic for high-speed cascading and features a single clock input that increments or decrements the count on each positive-going transition.
This IC is widely used in digital systems for programmable timing, frequency synthesis, and reversible counting applications. It is a staple in Arduino electronics projects in India for creating reversible binary counters, digital control systems, and multi-stage counting chains.
