74F269  
8-Bit Bidirectional Binary Counter  
General Description  
Features  
Synchronous counting and loading  
The 74F269 is  
a
fully synchronous 8-stage up/down  
counter featuring a preset capability for programmable  
operation, carry lookahead for easy cascading and a U/D  
input to control the direction of counting. All state changes,  
whether in counting or parallel loading, are initiated by the  
rising edge of the clock.  
Built-in lookahead carry capability  
Count frequency 100 MHz  
Supply current 113 mA typ  
300 mil slimline package
