Overview
The MC14018BDR2G is a presettable divide-by-N counter produced by onsemi. This integrated circuit contains five Johnson counter stages that are asynchronously presettable and resettable. The counters are synchronous and increment on the positive going edge of the clock. The device is designed for flexibility, allowing division by any number from 2 to 10 through appropriate connections of the Q outputs to the data input.
The MC14018BDR2G is available in a SOIC-16 package and is Pb-free and RoHS compliant, making it suitable for a wide range of applications, including automotive and other environments requiring unique site and control change requirements.
