3V High Speed Bus Switching and Bus Isolation FUNCTIONAL BLOCK DIAGRAM 2 1A1 18 SW 1B1 DESCRIPTION: The octal bus switch has standard 244 pinouts.
The CBTLV3244 is designed for asynchronous communication between data buses.
Sets of four switches are controlled by one output Enable (OE).
When OE is low, the set of four bus switches is on and port A is connected to port B.
When OE is high, the set of four bus switches 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, both OEs should be tied to VCC through a pullup resistor.
