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 allows Ultra small MicroPak Pb-Free leadless package inputs to be connected to outputs with minimal propagation delay and without generating additional ground bounce noise. 5 switch connection between two ports The device is organized as a 1-bit switch with a bus enable (OE) Designed to be used in level-shifting applications signal. 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 Minimal propagation delay through the switch high-impedance state exists between the two ports. Reduced Low I CC voltage drive to the gate of the FET switch permits nominal level shifting of 5V to 3.3V through the switch. 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 NC7SZD384M5X MA05B 8Z4D 5-Lead SOT23, JEDEC MO-178, 1.6mm 3k Units on Tape and Reel NC7SZD384P5X MAA05A Z4D 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel NC7SZD384L6X MAC06A A4 Pb-Free 6-Lead MicroPak, 1.0mm Wide 5k Units on Tape and Reel Pb-Free package per JEDEC J-STD-020B.
