UP/DOWN COUNTER  
WITH PRESET  
AND RIPPLE CLOCK  
The MC74AC190 is a reversible BCD (8421) decade counter which features  
synchronous counting and asynchronous presetting. The preset feature allows  
the MC74AC190 to be used in programmable dividers. The Count Enable input,  
the Terminal Count output and the Ripple Clock output make possible a variety  
of methods of implementing multistage counters. In the counting modes, state  
changes are initiated by the rising edge of the clock.
