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 volt- A and B side outputs have equivalent 26: series age (2.5V or 3.3V) V applications with capability of inter- CC resistors facing to a 5V signal environment. The device is byte 5.3 ns t max (V 3.3V), 20 PA I max controlled. Each byte has separate control inputs which PD CC CC could be shorted together for full 16-bit operation. The T/R Power down high impedance inputs and outputs inputs determine the direction of data flow through the Supports live insertion/withdrawal (Note 1) device. The OE inputs disable both the A and B ports by Flow through pinout placing them in a high impedance state. Implements proprietary noise/EMI reduction circuitry In addition, all A and B outputs include equivalent 26: Latch-up performance exceeds 500 mA (nominal) series resistors to reduce overshoot and under- shoot and are designed to sink/source up to 12 mA at ESD performance: V 3.0V. CC Human body model 2000V The LCXR162245 is fabricated with an advanced CMOS Machine model 200V technology to achieve high speed operation while maintain- Note 1: To ensure the high-impedance state during power up or down OE ing CMOS low power dissipation. 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.
