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 Fully Configurable: Inputs and Outputs Track V CC allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the V level and the CCA Non-Preferential Power-Up Either V May Be CC B port tracks the V level. This allows for bi-directional CCB Powered Up First voltage translation over a variety of voltage levels: 1.2V, Outputs Switch to 3-State if Either V is at GND CC 1.5V, 1.8V, 2.5V, and 3.3V. Power-Off Protection The device remains in three-state as long as either V =0V, allowing either V to be powered up first. CC CC Bus-Hold on Data Inputs Eliminates the Need for Internal power-down control circuits place the device in Pull-Up Resistors Do Not Use Pull-Up Resistors on 3-state if either V is removed. CC A or B Ports The /OE input, when HIGH, disables both the A and B Control Input (/OE) Referenced to V Voltage CCA ports by placing them in a 3-state condition. The /OE Packaged in 20-Terminal DQFN (2.5mm x 4.5mm) input is supplied by V . CCA Direction Control Not Necessary The FXLA108 supports bi-directional translation without the need for a direction control pin. The two ports of the 100Mbps Throughput when Translating Between device have auto-direction sense capability. Either port 1.8V and 2.5V may sense an input signal and transfer it as an output ESD Protection Exceeds: signal to the other port. - 8kV HBM (per JESD22-A114 &Mil Std 883e 3015.7) - 2kV CDM (per ESD STM 5.3) Applications Laptops, Notebooks, Routers, Switches Ordering Information Operating Part Number Package Packing Method Temperature Range FXLA108BQX -40 to 85C 20-Terminal DQFN 2.5mm x 4.5mm Package 3K Units Tape and Reel 2009 Fairchild Semiconductor Corporation www.fairchildsemi.com FXLA108 Rev. 1.0.5
