DESCRIPTION  
The M54/74HC4518/4520 are high speed CMOS  
DUAL 4 BIT BINARY COUNTERS fabricated in sili-  
con gate C2MOS technology. They have the same  
high speed performance of LSTTL combined with  
true CMOS low power consumption.  
They consists of two identical internally syn-  
chronous 4-stage counters. The counter stages are  
D-type flip-flops having interchangeable Clock and  
ENABLE inputs for incrementing on either the posi-  
tive-going or negative-going transition.  
For single-unit operation the ENABLE input is main-  
tained ”high” and the counter advances on each  
positive-going transition of the CLOCK. The  
counters are cleared by high levels on their clear  
lines. The counter can be cascaded in the ripple  
mode by connecting Q4 to the enable input of the  
subsequent counter whilethe clock input ofthe latter  
is held permanently low.  
NC =  
All inputs are equipped with protection circuits  
against static discharge and transient excess volt-  
age.
