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.

Fully Configurable: Inputs and Outputs Track V CC The device allows translation between voltages as high as 5.5V to as low as 1.65V. The A port tracks the V CCA Non-Preferential Power-Up Either V may be CC level and the B port tracks the V level. This allows for CCB Powered-Up First bi-directional voltage translation over a variety of Outputs Remain in 3-State Until Active V Level is CC voltage levels: 1.8V, 2.5V, 3.3V, and 5.0V. Reached The device remains in 3-state until both V s reach CC Outputs Switch to 3-State if Either V is at GND CC active levels, allowing either V to be powered-up first. CC Internal power-down control circuits place the device in Power-Off Protection 3-state if either V is removed. CC Bus Hold On Data Inputs Eliminates the Need for The /OE input, when high, disables both the A and B Pull-Up Resistors Side by placing them in a 3-state condition. The /OE Control Input (/OE) is Referenced to V Voltage CCA input is supplied by V . CCA Packaged in 20-Terminal DQFN The FXMA108 supports bi-directional translation without the need for a direction control pin. The two sides of the Direction Control Not Needed device have auto-direction-sense capability. Either port 80Mbps Throughput when Translating between may sense an input signal and transfer it as an output 2.5V and 5.0V signal to the other port.
