Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

The low On Voltage level shifting Resistance of the switch allows inputs to be connected to Minimal propagation delay through the switch outputs without adding propagation delay or generating Low l CC additional ground bounce noise. A diode to V has been CC Zero bounce in flow-through mode integrated into the circuit to allow for level shifting between 5V inputs and 3.3V outputs. Control inputs compatible with TTL level The device is organized as a 12-bit or 24-bit bus switch. Also packaged in plastic Fine-Pitch Ball Grid Array When OE is LOW, the switch is ON and Port 1A is con- 1 (FBGA) nected to Port 1B. When OE is LOW, Port 2A is connected 2 to Port 2B. When OE is HIGH, a high impedance state 1/2 exists between the A and B Ports.
