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 Minimal propagation delay through the switch resistance of the switch allows inputs to be connected to Ultra low power with < 0.1 A typical I CC outputs without adding propagation delay or generating Zero ground bounce in flow-through mode additional ground bounce noise. The device is organized as two 5-bit switches with separate bus enable (OE) sig- Control inputs compatible with TTL level nals. When OE is LOW, the switch is ON and Port A is con- nected to Port B. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.
