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.

(V = 3.3V), 10A I max. PD CC CC Power down high impedance inputs and outputs The LCX573 is functionally identical to the LCX373 but (1) has inputs and outputs on opposite sides. Supports live insertion/withdrawal 24mA output drive (V = 3.0V) The LCX573 is designed for low voltage applications CC with capability of interfacing to a 5V signal environment. Implements proprietary noise/EMI reduction circuitry The LCX573 is fabricated with an advanced CMOS Latch-up performance exceeds JEDEC 78 conditions tech- nology to achieve high speed operation while ESD performance maintaining CMOS low power dissipation. Human body model > 2000V Machine model > 200V 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.
