description/ordering information  
The SN74CBT3345 provides eight bits of  
high-speed TTL-compatible bus switching in a  
standard ’245 device pinout. The low on-state  
resistance of the switch allows connections to be  
made with minimal propagation delay.  
The device is organized as one 8-bit switch bank  
with dual output-enable (OE and OE) inputs.  
When OE is low or OE is high, the switch is on, and  
port A is connected to port B. When OE is high and  
OE is low, the switch is open, and the  
high-impedance state exists between the two  
ports.
