Description  
• Positive or Negative Edge Triggering  
• Synchronous Internal Carry Propagation  
• Fanout (Over Temperature Range)  
The Harris CD74HC4518 is a dual BCD up-counter. The  
Harris CD74HC4520 and CD74HCT4520 are dual binary  
up-counters. Each device consists of two independent  
internally synchronous 4-stage counters. The counter stages  
are D-type flip-flops having interchangeable CLOCK and
