Features  
Description  
• Fully Static Operation  
• Buffered Inputs  
The ’HC393 and ’HCT393 are 4-stage ripple-carry binary  
counters. All counter stages are master-slave flip-flops. The  
state of the stage advances one count on the negative  
transition of each clock pulse; a high voltage level on the MR  
line resets all counters to their zero state. All inputs and  
outputs are buffered.
