The MC14521B consists of a chain of 24 flip–flops with an input  
circuit that allows three modes of operation. The input will function as  
a crystal oscillator, an RC oscillator, or as an input buffer for an  
external oscillator. Each flip–flop divides the frequency of the  
24  
previous flip–flop by two, consequently this part will count up to 2  
=

16,777,216. The count advances on the negative going edge of the  
clock. The outputs of the last seven–stages are available for added  
flexibility.

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
