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.


Description

The octal bus switch has standard 245 pinouts. 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 IDT74CBTLV3245 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 IDT74CBTLV3245 should be tied to VCC through a pullup resistor.
