MM74HCA390 Dual 4-Bit Decade Counter/  
MM74HCA393 Dual 4-Bit Binary Counter  
General Description  
These counter circuits contain independent ripple carry  
counters and utilize advanced silicon-gate CMOS technolo-  
gy. The MM74HCA390 incorporates dual decade counters,  
tionally as well as pin equivalent to the 74LS390/74LS393.  
All inputs are protected from damage due to static dis-  
charge by diodes to V  
and ground.  
CC  
each composed of  
a divide-by-two and a divide-by-five  
counter. The divide-by-two and divide-by-five counters can  
be cascaded to form dual decade, dual bi-quinary, or vari-  
ous combinations up to a single divide-by-100 counter. The  
MM74HCA393 contains two 4-bit ripple carry binary coun-  
ters, which can be cascaded to create a single divide-by-  
256 counter.

Each of the two 4-bit counters is incremented on the high to  
low transition (negative edge) of the clock input, and each  
has an independent clear input. When clear is set high all  
four bits of each counter are set to a low level. This enables  
count truncation and allows the implementation of divide-by-  
N counter configurations.
