Up/Down Decade Counter with Preset and Ripple Clock  
General Description  
Features  
Y
High-speedÐ125 MHz typical count frequency  
The ’F190 is a reversible BCD (8421) decade counter fea-  
turing synchronous counting and asynchronous presetting.  
The preset feature allows the ’F190 to be used in program-  
mable 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.
