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.

Each output is disabled 2.3V3.6V V specifications provided CC when the associated output-enable (OE) input is LOW. 5.5ns t max. (V = 3.3V), 10A I max. PD CC CC The inputs tolerate voltages up to 7V allowing the inter- Power down high impedance inputs and outputs face of 5V systems to 3V systems. (1) Supports live insertion/withdrawal The 74LCX126 is fabricated with an advanced CMOS 24mA output drive (V = 3.0V) CC technology to achieve high speed operation while main- Implements proprietary noise/EMI reduction circuitry taining CMOS low power dissipation. Latch-up performance exceeds JEDEC 78 conditions ESD performance: Human body model > 2000V Machine model > 100V Leadless DQFN package Note: 1. To ensure the high-impedance state during power up or down, OE should be tied to V through a pull-up CC resistor: the minimum value of the resistor is determined by the current-sourcing capability of the driver.
