Dual Decade Ripple Counter  
Features  
Description  
• Two BCD Decade or Bi-Quinary Counters  
The CD74HC390 and ’HCT390 dual 4-bit decade ripple  
counters are high-speed silicon-gate CMOS devices and are  
pin compatible with low-power Schottky TTL (LSTTL). These  
devices are divided into four separately clocked sections.  
The counters have two divide-by-2 sections and two divide-  
by-5 sections. These sections are normally used in a BCD  
decade or bi-quinary configuration, since they share a com-  
mon master reset (nMR). If the two master reset inputs (1MR  
and 2MR) are used to simultaneously clear all 8 bits of the  
counter, a number of counting configurations are possible  
within one package. The separate clock inputs (nCP0 and  
nCP1) of each section allow ripple counter or frequency divi-  
sion applications of divide-by-2, 4. 5, 10, 20, 25, 50 or 100.  
Each section is triggered by the High-to-Low transition of the  
input pulses (nCP0 and nCP1).  
• One Package Can Be Configured to Divide-by-2, 4,  
5,10, 20, 25, 50 or 100

For BCD decade operation, the nQ0 output is connected to  
the nCP1 input of the divide-by-5 section. For bi-quinary  
decade operation, the nO3 output is connected to the nCP0

The master reset inputs (1MR and 2MR) are active-High  
asynchronous inputs to each decade counter which oper-  
ates on the portion of the counter identified by the “1” and “2”  
prefixes in the pin configuration. A High level on the nMR  
input overrides the clock and sets the four outputs Low.
