The 74HC4520D,112 part from Nexperia is an IC (integrated circuit) device that contains two 4-bit binary counters, each with its own asynchronous clear, preset, and clock inputs. Each counter also includes two outputs, QA and QB, which can be used to control external signals or devices. This device has a propagation delay of 11.5 ns and a supply voltage range of 2 V - 6 V. It can operate at temperatures ranging from -40° C to 85° C. The 74HC4520D,112 is an ideal part for applications such as frequency division, pulse-width modulation, and time delay generation.
