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 device is fabricated with advanced sub-micron CMOS technology to achieve high speed enable and disable MicroPak Pb-Free leadless package times and low On Resistance over a broad V range. The CC Typical 7 On Resistance 5V V CC device is specified to operate over the 1.65 to 5.5V V operat- CC ing range. The device is organized as a dual switch with inde- Broad V operating range: 1.65V to 5.5V CC pendent CMOS compatible switch enable (OE) controls. When Rail-to-Rail signal handling OE is HIGH, the switch is ON and Port A is connected to Port B. When OE is LOW, the switch is OPEN and a high-impedance Power down high impedance control inputs state exists between the two ports. The enable inputs tolerate Control inputs are overvoltage tolerant voltages up to 5.5V independent of the V operating range. CC Control inputs are CMOS compatible 300 MHz 3dB bandwidth Ordering Code: Product Order Package Code Package Description Supplied As Number Number Top Mark FSA266K8X MAB08A WB66 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide 3K Units on Tape and Reel FSA266L8X MAC08A P4 Pb-Free 8-Lead MicroPak, 1.6 mm Wide 5K Units on Tape and Reel NC7WB66K8X MAB08A WB66 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide 3K Units on Tape and Reel NC7WB66L8X MAC08A P4 Pb-Free 8-Lead MicroPak, 1.6 mm Wide 5K Units on Tape and Reel Pb-Free package per JEDEC J-STD-020B.
