The 74CBTLV3245 octal bus switch has standard 245 pinouts and is designed for asynchronous communication between data buses. When the 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. The 74CBTLV3245 operates at -40°C to +85°C.
