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. These complementary  
MOS up counters find primary use in multi–stage synchronous or  
ripple counting applications requiring low power dissipation and/or  
high noise immunity.

This device contains protection circuitry to guard against damage due to high  
static voltages or electric fields. However, precautions must be taken to avoid  
applications of any voltage higher than maximum rated voltages to this  
high–impedancecircuit. For proper operation, V and V should be constrained
