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 information presented 7.5ns t max. (V = 3.3V), 10A I max. PD CC CC to the D inputs is stored in the flip-flops on the LOW-to- Power down high impedance inputs and outputs HIGH Clock (CP) transition. (1) Supports live insertion/withdrawal The LCX574 is functionally identical to the LCX374 24mA output drive (V = 3.0V) CC except for the pinouts. Implements proprietary noise/EMI reduction circuitry The LCX574 is designed for low voltage applications Latch-up performance exceeds JEDEC 78 conditions with capability of interfacing to a 5V signal environment. ESD performance The LCX574 is fabricated with an advanced CMOS Human body model > 2000V technology to achieve high speed operation while main- Machine model > 200V taining CMOS low power dissipation. 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.
