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 a high-impedance state exists between the two ports.  
The SN74CBT3345 is characterized for operation from 0°C to 70°C.
