description/ordering information  
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.  
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 the high-impedance state exists  
between the two ports.  
This device is fully specified for partial-power-down applications using I . The I feature ensures that  
off  
off  
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 up or power down, OE should be tied to V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
