ON Semiconductor MC74ACT161DG: 4-Bit Binary Counter

The MC74ACT161DG from ON Semiconductor is a high-performance, 4-bit binary counter integrated circuit, designed for use in a wide array of electronic applications requiring precise timing and counting solutions. Fabricated with advanced CMOS technology, this device offers a robust combination of speed, functionality, and low power consumption, making it an ideal choice for designers working on modern digital systems.

This versatile counter features a fully synchronous design, ensuring that the outputs change coincident with each other on the rising edge of the clock pulse. The synchronous design provides improved performance over asynchronous counterparts, especially in terms of speed and reliability. The MC74ACT161DG operates from a standard 5V supply, and its compatibility with TTL levels allows for easy interfacing with other logic families.

The device includes features such as a clear function to reset the count to zero, and preset capabilities that allow the counter to be initialized to any desired value. The counter advances on the rising edge of the clock signal, and the built-in look-ahead carry capability allows for high-speed counting without the need for additional circuitry. This makes the MC74ACT161DG particularly well-suited for high-speed machine and process control applications, as well as for use in counters, timers, and frequency dividers.

The MC74ACT161DG is packaged in a narrow-body, 16-pin SOIC package, which is conducive to space-constrained applications. Its operating temperature range from -40°C to +85°C ensures reliable performance in a variety of environmental conditions. Furthermore, the device is fully static, which means that the clock can be stopped at any time without loss of data.

ON Semiconductor's commitment to quality is evident in the MC74ACT161DG, which is manufactured to stringent standards, ensuring consistent and reliable operation for the life of the product. Whether used in industrial control systems, consumer electronics, or communication devices, the MC74ACT161DG provides a dependable and efficient solution for your digital counting needs.
