The SN74CBT6800A provides ten bits of  
high-speed TTL-compatible bus switching. The  
low on-state resistance of the switch allows  
bidirectional connections to be made while adding  
near-zero propagation delay. The device also  
precharges the B port to a user-selectable  
bias voltage (BIASV) to minimize live-insertion  
noise.

BIASV  
The SN74CBT6800A is organized as one 10-bit switch with a single enable (ON) input. When ON is low, the  
switch is on, and port A is connected to port B. When ON is high, the switch between port A and port B is open.  
When ON is high or V  
is 0 V, B port is precharged to BIASV through the equivalent of a 10-kresistor.
