The SN74CBTLV16210 provides 20 bits of  
high-speed bus switching. The low on-state  
resistance of the switch allows connections to be  
made with minimal propagation delay.

The device is organized as dual 10-bit bus  
switches with separate output-enable (OE)  
inputs. It can be used as two 10-bit bus switches  
or as one 20-bit bus switch. When OE is low, the  
associated 10-bit bus switch is on, and port A is  
connected to port B. When OE is high, the switch  
is open, and the high-impedance state exists  
between the two ports.

This  
device  
is  
fully  
specified  
for  
partial-power-down applications using I . The I  
off  
off  
feature ensures that damaging current will not  
backflow through the device when it is powered  
down. The device has isolation during power off.  
To ensure the high-impedance state during power  
NC − No internal connection  
up or power down, OE should be tied to V  
CC  
through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking  
capability of the driver.
