The CBTLV3245 is designed for asynchronous communication between data buses. 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 off and a high impedance exists between Port A and Port B. To ensure the high-impedance state during power up or power down, OE should be tied to V CC through a pullup resistor.
