15 2B1  
The SN74CBT3384A provides ten bits of  
high-speed TTL-compatible bus switching. The  
low on-state resistance of the switch allows  
connections to be made with minimal propagation  
delay.

2OE  
The device is organized as two 5-bit switches with separate output-enable (OE) inputs. 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 a high-impedance state  
exists between the two ports.  
The SN74CBT3384A is characterized for operation from –40°C to 85°C.
