SN74HC161N, 4-Bit Synchronous Binary Counter, DIP-16

The SN74HC161N is a high-speed 4-bit synchronous binary counter, designed for use in digital frequency division, counting, and sequencing applications. With an internal carry look-ahead mechanism, the counter provides high-speed cascading with minimal delay. The counter advances on the rising edge of the clock pulse when enabled, ensuring synchronous operation without counting glitches. Operating at 2V to 6V, the SN74HC161N supports a maximum clock frequency of 36 MHz, making it well-suited for high-speed timing and counting applications. The device features asynchronous clear and synchronous load functions, enabling easy presetting to specific values. Encased in a DIP-16 package, the SN74HC161N is ideal for breadboarding, prototyping, and through-hole PCB designs. It is commonly used in timing circuits, digital counters, and embedded control systems.
