description  
NC – No internal connection  
The ’LV4040A devices are 12-bit asynchronous  
binary counters with the outputs of all stages  
availableexternally. A high level at the clear (CLR)  
input asynchronously clears the counter and  
resets all outputs low. The count is advanced on  
a high-to-low transition at the clock (CLK) input.  
Applications include time-delay circuits, counter  
controls, and frequency-dividing circuits.  
The SN54LV4040A is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74LV4040A is characterized for operation from –40°C to 85°C.
