Features  
Description  
• Fully Static Operation  
• Buffered Inputs  
The ’HC4040 and ’HCT4040 are 14-stage ripple-carry  
binary counters. All counter stages are master-slave flip-  
flops. The state of the stage advances one count on the  
negative clock transition of each input pulse; a high voltage  
level on the MR line resets all counters to their zero state. All  
inputs and outputs are buffered.
