Features  
General Description  
High-Speed—125MHz typical count frequency  
Synchronous counting  
The 74F191 is a reversible modulo-16 binary counter  
featuring synchronous counting and asynchronous pre-  
setting. The preset feature allows the 74F191 to be used  
in programmable dividers. The Count Enable input, the  
Terminal Count output and Ripple Clock output make  
possible a variety of methods of implementing multistage  
counters. In the counting modes, state changes are initi-  
ated by the rising edge of the clock.
