description/ordering information  
The  
’HC193  
devices  
are  
4-bit  
synchronous,  
reversible,  
up/down  
binary  
counters.  
Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change  
coincidentally with each other when so instructed by the steering logic. This mode of operation eliminates the  
output counting spikes normally associated with asynchronous (ripple-clock) counters.
