The MC14526B binary counter is constructed with MOS P–channel  
and N–channel enhancement mode devices in a monolithic structure.  
This device is presettable, cascadable, synchronous down counter  
with a decoded “0” state output for divide–by–N applications. In  
single stage applications the “0” output is applied to the Preset Enable  
input. The Cascade Feedback input allows cascade divide–by–N  
operation with no additional gates required. The Inhibit input allows  
disabling of the pulse counting function. Inhibit may also be used as a  
negative edge clock.  
This complementary MOS counter can be used in frequency  
synthesizers, phase–locked loops, and other frequency division  
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
