MC14521B  
24−Stage Frequency Divider  
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 previous flip−flop  
24  
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.

Stresses exceeding Maximum Ratings may damage the device. Maximum  
Ratings are stress ratings only. Functional operation above the Recommended  
Operating Conditions is not implied. Extended exposure to stresses above the  
Recommended Operating Conditions may affect device reliability.

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−impedance circuit. For proper operation, V and V should be constrained
