CY74FCT191T  
SCCS016 - May 1994 - Revised February 2000  
4-Bit Up/Down Binary Counter  
Features  
Functional Description  
• Function, pinout, and drive compatible with FCT and F  
logic  
• FCT-C speed at 6.2 ns max,  
FCT-A speed at 7.8 ns max.  
• Reduced VOH (typically = 3.3V) versions of equivalent  
FCT functions  
• Edge-rate control circuitry for significantly improved  
noise characteristics  
The FCT191T is a reversible modulo-16 binary counter,  
featuring synchronous counting and asynchronous presetting.  
The preset allows the FCT191T to be used in programmable  
dividers. The count enable input, terminal count output, and ripple  
clock output make possible a variety of methods of implementing  
multiusage counters. In the counting modes, state changes are  
initiated by the rising edge of the clock.  
The outputs are designed with a power-off disable feature to  
allow for live insertion of boards.  
• Power-off disable permits live insertion  
• ESD > 2000V  
Matched rise and fall times  
• Sink current
