description  
The SN74CBT16245 device provides 16 bits of  
high-speed TTL-compatible bus switching in a  
standard ’16245 device pinout. The low on-state  
resistance of the switch allows connections to be  
made with minimal propagation delay.  
V
V
The device is organized as two 8-bit low-impedance  
switches with separate output-enable (OE) inputs.  
When OE is low, the switch is on, and data can  
flow from the A port to the B port, or vice versa.  
When OE is high, the switch is open, and the  
high-impedance state exists between the two  
ports.
