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.

Supports live insertion/withdrawal (Note 1) The LCX821 is fabricated with an advanced CMOS tech- nology to achieve high speed operation while maintaining 24 mA output drive (V = 3.0V) CC CMOS low power dissipation. Implements patented noise/EMI reduction circuitry Latch-up performance exceeds 500 mA ESD performance: Human Body Model > 2000V Machine Model > 200V Note 1: To ensure the high-impedance state during power up or down, OE should be tied to V through a pull-up resistor: the minimum value or the CC resistor is determined by the current-sourcing capability of the driver.
