MOTOROLA SEMICONDUCTOR TECHNICAL DATA Dual Up Counters The MC14518B dual BCD counter and the MC14520B dual binary counter are constructed with MOS P–channel and N–channel enhancement mode devices in a single monolithic structure.
Each consists of two identical, independent, internally synchronous 4–stage counters.
The counter stages are type D flip–flops, with interchangeable Clock and Enable lines for incrementing on either the positive–going or negative–going transition as required when cascading multiple stages.
Each counter can be cleared by applying a high level on the Reset line.
In addition, the MC14518B will count out of all undefined states within two clock periods.
