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 Resistance of the switch Ultra small MicroPak leadless package allows inputs to be connected to outputs with minimal propaga- tion delay and without generating additional ground bounce 5 switch connection between two ports noise. The device is organized as a 1-bit switch with a bus Minimal propagation delay through the switch enable (OE) signal. When OE is LOW, the switch is on and Port A is connected to Port B. When OE is HIGH, the switch is open Low I CC and a high-impedance state exists between the two ports. Zero bounce in flow-through mode Control inputs compatible with TTL level Ordering Code: Order Package Product Code Package Description Supplied As Number Number Top Mark NC7SZ384M5X MA05B 8Z84 5-Lead SOT23, JEDEC MO-178, 1.6mm 3k Units on Tape and Reel NC7SZ384P5X MAA05A Z84 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel NC7SZ384L6X MAC06A C3 Pb-Free 6-Lead MicroPak, 1.0mm Wide 5k Units on Tape and Reel Pb-Free package per JEDEC J-STD-020B.
