DESCRIPTION  
The M54/74HC390 is a high speed CMOS DUAL  
DECADE COUNTER fabricated in silicon gate  
C2MOS technology. It has the same highspeed per-  
formance of LSTTL combined with true CMOS low  
power consumption.  
This dual decade counter contains two independent  
ripple carry counters. Each counter is composed of  
a divide-by-two and divide-by-five counter. The  
divide-by-two and divide-by-five counters can be  
cascaded to form dual decade, dual biquinary, or  
various combinations up to a single divide-by-100  
counter.  
Each 4-bit counter 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 low all four bits of each counter are set to low.  
This enables count truncation and allows the im-  
plementation of divide-by-N counter configurations.  
NC =  
No Inter-  
nal Con-  
All inputs are equipped with protection circuits  
against static discharge and transient excess volt-  
age.
