74F190  
Up/Down Decade Counter with Preset and Ripple Clock  
General Description  
Features  
The 74F190 is a reversible BCD (8421) decade counter  
featuring synchronous counting and asynchronous preset-  
ting. The preset feature allows the 74F190 to be used in  
programmable dividers. The Count Enable input, the Termi-  
nal Count output and the Ripple Clock output make possi-  
High-speed—125 MHz typical count frequency  
Synchronous counting  
Asynchronous parallel load  
Cascadable  
ble  
a variety of methods of implementing multistage  
counters. In the counting modes, state changes are initi-  
ated by the rising edge of the clock.
