10-Bit Bus Switch with Pre-Charged Outputs  
and 2V Undershoot Hardened Circuit (UHC ) Protection  
General Description  
Features  
4switch connection between two ports.  
The Fairchild Switch FSTU6800 provides 10-bits of high-  
speed CMOS TTL-compatible bus switching. The low on  
resistance of the switch allows inputs to be connected to  
outputs without adding propagation delay or generating  
additional ground bounce noise. Both the A Ports and the B  
Ports are “undershoot hardened” with UHC protection to  
support an extended input range to 2.0V below ground.  
Fairchild’s integrated Undershoot Hardened Circuit, UHC  
senses undershoot at the I/Os, and responds by preventing  
voltage differentials from developing and turning on the  
switch. The device also precharges the B Port to a select-  
able bias voltage (BiasV) to minimize live insertion noise.  
Undershoot Hardened to -2.0V.  
Soft enable turn-on to minimize bus-to-bus charge  
sharing during enable.  
Low lCC  
.
Zero bounce in flow-through mode.  
Output precharge to minimize live insertion noise.  
Control inputs compatible with TTL level.  
See Applications Note AN-5008 for details.  
The device is organized as a 10-bit switch with a bus  
enable (OE) signal. 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 the B Port is precharged to BiasV  
through an equivalent 10-kresistor.
