description

The ’CBT16244 devices provide 16 bits of  
high-speed TTL-compatible bus switching in a  
standard ’16244 device pinout. The low on-state  
resistance of the switch allows connections to be  
made with minimal propagation delay.

These devices are organized as four 4-bit  
low-impedance  
switches  
with  
separate  
output-enable (OE) inputs. When OE is low, the  
switch is on, and data can flow from port A to port  
B, or vice versa. When OE is high, the switch is  
open, and the high-impedance state exists  
between the two ports.
