Description  
The CD74HC4518 is a dual BCD up-counter. The ’HC4520  
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  
NOTE: When ordering, use the entire part number. The suffix 96  
denotes tape and reel. The suffix T denotes a small-quantity reel  
of 250.
