SEMICONDUCTOR TECHNICAL DATA  
L SUFFIX  
CERAMIC  
CASE 620  
The MC14020B 14–stage binary counter is constructed with MOS  
P–channel and N–channel enhancement mode devices in a single  
monolithic structure. This part is designed with an input wave shaping circuit  
and 14 stages of ripple–carry binary counter. The device advances the count  
on the negative–going edge of the clock pulse. Applications include time  
delay circuits, counter controls, and frequency–dividing circuits.
