The SN74CBTD16211 provides 24 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. A diode to V  
is integrated in the circuit to  
CC  
allow for level shifting between 5-V inputs and  
3.3-V outputs.  
The device is organized as a dual 12-bit bus  
switch with separate output-enable (OE) inputs. It  
can be used as two 12-bit bus switches or as one  
24-bit bus switch. When OE is low, the associated  
12-bit bus switch is on and A port is connected to  
B port. When OE is high, the switch is open, and  
a high-impedance state exists between the ports.
