GND  
The SN74CBTLV6800 provides 10 bits of  
high-speed bus switching. The low on-state  
resistance of the switch allows connections to be  
made with minimal propagation delay. The device  
also precharges the B port to a user-selectable  
bias voltage (BIASV) to minimize live-insertion  
noise.  
B10  
BIASV  
The device is organized as a single 10-bit bus switch with an output-enable (OE) input. When OE is low, the  
10-bit bus switch is on and port A is connected to port B. When OE is high, the switch is open, the  
high-impedance state exists between the two ports, and port B is precharged to BIASV through the equivalent  
of a 10-kresistor.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
The SN74CBTLV6800 is characterized for operation from –40°C to 85°C.
