The 74F160A functions as a 4-bit synchronous decade counter. All state changes are synchronized to the rising edge of the clock input. The device features parallel load inputs that allow the counter to be preset to any desired value. A clear input provides a means for asynchronously resetting the counter to zero. A carry output is provided for cascading multiple counters to achieve higher counting ranges. The synchronous operation ensures that all flip-flops change state simultaneously, providing a clean and glitch-free counting operation. The carry output simplifies the cascading of multiple counters, making it easy to implement counters with virtually unlimited counting ranges. The 74F160A is supplied in a 16-pin DIP or SOIC package. The device operates from a single 5V power supply. It exhibits a typical propagation delay of a few nanoseconds, making it suitable for high-speed applications. The device is also available in surface mount packages for high-density circuit board designs. The 74F160A is a reliable and versatile building block for digital counting applications.
