MC14572UB

The MC14572UB is a high-performance CMOS dual 4-bit binary counter manufactured by onsemi. It features two independent 4-bit counters that can be configured for various counting modes, including up, down, or up/down operations, making it highly versatile for digital timing and control applications. Each counter includes a carry output (CO) and a borrow output (BO), enabling cascading to create larger counter systems without external logic. This device operates over a wide supply voltage range of 3.0 V to 15 V, offering flexibility in power design across different systems. Its low power consumption, typical of CMOS technology, makes it ideal for battery-powered or energy-efficient devices. The IC supports both synchronous and asynchronous reset functions, allowing precise control over counter initialization and operation. Additionally, the MC14572UB includes enable inputs for each counter, providing further control over when counting occurs—essential for minimizing unnecessary switching and power use. Designed with robust noise immunity and stable performance under varying environmental conditions, the MC14572UB is suitable for industrial, automotive, and consumer electronics environments. It features TTL-compatible inputs and outputs, simplifying integration with other digital circuits. The dual counter architecture allows for simultaneous management of two separate timing or event-counting tasks within a single package, reducing board space and component count. Common applications include frequency division, pulse generation, time interval measurement, motor speed control, and sequential logic control in equipment such as digital clocks, timers, test instruments, and instrumentation systems. Its ability to handle both positive and negative edge triggering adds versatility in signal processing scenarios where precise timing is critical. The MC14572UB is available in a 16-pin DIP package, facilitating easy mounting and prototyping. With its reliable performance, low quiescent current, and compatibility with standard logic families, this integrated circuit remains a preferred choice for engineers designing compact, efficient, and scalable digital systems.
