Quality Control: Learn More
The onsemi 74HC161ADG is a high-speed silicon-gate CMOS device, a synchronous 4-bit binary counter featuring asynchronous preset capability. This component operates as a single 4-bit counter element with a maximum count rate of 35 MHz at 5V. Designed for positive edge triggering, it offers both carry-lookahead and ripple-carry outputs for cascading. The MC74HC161ADG includes synchronous count enable and clear functions, along with asynchronous parallel load (preset) inputs. Its robust design supports a wide operating voltage range of 2V to 6V and an industrial temperature range of -40°C to 85°C. The 16-SOIC package facilitates surface mounting for efficient board space utilization. This device finds application in digital logic systems, frequency division, and event counting across various industrial and consumer electronics sectors.
