Overview
The MC14518BDWR2G is a dual BCD counter produced by onsemi. This device is part of the MC14518B series, which consists of two identical, independent, internally synchronous 4-stage counters. Each counter stage is a type D flip-flop, allowing for interchangeable Clock and Enable lines to increment on either the positive-going or negative-going transition. This flexibility makes it suitable for various counting applications requiring low power dissipation and high noise immunity.
