4-Bit Bus Switch with 2V Undershoot Protection  
General Description  
Features  
The Fairchild Switch FSTU3125 provides four high-speed  
CMOS TTL-compatible bus switches. The low On Resis-  
tance of the switch allows inputs to be connected to out-  
puts without adding propagation delay or generating  
additional ground bounce noise. The A and B Ports are  
protected against undershoot to support an extended  
range to 2.0V below ground. Fairchild’s integrated Under-  
shoot Hardened Circuit (UHC ) senses undershoot at the  
I/O and responds by preventing voltage differentials from  
developing and turning the switch on.  
Undershoot hardened to 2V (A and B Ports)  
4switch connection between two ports  
Minimal propagation delay through the switch  
Low lCC  
Zero bounce in flow-through mode  
Control inputs compatible with TTL level  
See application notes AN-5008 and AN-5021 for details  
on undershoot  
The device is organized as four 1-bit switches with sepa-  
rate OE inputs. When OE is LOW, the switch is ON and  
Port A is connected to Port B. When OE is HIGH, the  
switch is OPEN and  
between the two ports.
