description  
The SN74CBTLV3245 provides eight bits of  
high-speed bus switching in a standard ’245  
device pinout. The low on-state resistance of the  
switch allows connections to be made with  
minimal propagation delay.  
NC – No internal connection  
The device is organized as one 8-bit switch. When output enable (OE) is low, the 8-bit bus 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.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
The SN74CBTLV3245 is characterized for operation from –40°C to 85°C.
