SEMICONDUCTOR TECHNICAL DATA  
L SUFFIX  
CERAMIC  
CASE 620  
The MC14029B Binary/Decade up/down counter is constructed with MOS  
P–channel and N–channel enhancement mode devices in a single  
monolithic structure. The counter consists of type D flip–flop stages with a  
gating structure to provide toggle flip–flop capability. The counter can be  
used in either Binary or BCD operation. This complementary MOS counter  
finds primary use in up/down and difference counting and frequency  
synthesizer applications where low power dissipation and/or high noise  
immunity is desired. It is also useful in A/D and D/A conversion and for  
magnitude and sign generation.
