General Description
IDT74CBTLV3244 General 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 OEis low, the set of four bus switches is on and port A is connected to port B. When OEis 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.

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
