4029 - Binary and BCD Counter

The 4029 is a versatile 4-bit binary/decade up/down counter. It features a selectable counting mode (binary or BCD), and direction control (up or down), with parallel load capability. It has asynchronous preset and carry/borrow outputs for cascading. Operating from 3V to 15V, it’s widely used in digital counting, timing, and sequencing applications. Its flexibility makes it ideal for complex counter designs.
