description  
The SN74CBTLV3245A 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.  
Thedeviceisorganizedasone8-bitswitch. Whenoutputenable(OE)islow, the8-bitbusswitchisonandA port  
is connected to B port. When OE is high, the switch is open and the 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 SN74CBTLV3245A is characterized for operation from –40°C to 85°C.
