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 designed for low 7.0ns t max. (V = 3.3V), 10A I max. PD CC CC voltage (2.5V and 3.3V) V applications with capability CC Power down high impedance inputs and outputs of interfacing to a 5V signal environment. The T/R input (1) Supports live insertion/withdrawal determines the direction of data flow through the device. 24mA output drive (V = 3.0V) The OE input disables both the A and B ports by placing CC them in a high impedance state. Implements proprietary noise/EMI reduction circuitry Latch-up performance exceeds 500mA The LCX245 is fabricated with an advanced CMOS tech- nology to achieve high speed operation while maintain- ESD performance: ing 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 or the resistor is determined by the current-sourcing capability of the driver.
