Overview
The MC14520BDWG is a dual binary up counter produced by onsemi. This integrated circuit is constructed with MOS P-channel and N-channel enhancement mode devices in a single monolithic structure. It consists of two identical, independent, internally synchronous 4-stage counters, each of which can be cleared by applying a high level on the Reset line. The counters are designed for low power dissipation and high noise immunity, making them suitable for various counting applications.
