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 Track V Level 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. Both ports are designed to CCB Powered-up First accept supply voltage levels from 1.1V to 3.6V. This Outputs Remain in 3-State until Active V Level is CC allows for bi-directional voltage translation over a variety Reached of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. Outputs Switch to 3-State if Either V is at GND CC The device remains in 3-state until both V s reach CC active levels, allowing either V to be powered-up first. CC Bushold on Data Inputs Eliminates the need for The device also contains power-down control circuits External Pull-Up / Pull-Down Resistors that place the device in 3-state if either V is removed. CC 26W Output Series Resistors on the B Port to The Transmit/Receive (T/R) input determines the Reduce Line Noise direction of data flow through the device. The OE input, Power-Off Protection when HIGH, disables both the A and B ports by placing them in a 3-state condition. The FXLH42245 is Control Inputs (T/R, OE) Levels are Referenced To designed with the control pins (T/R and OE) supplied by V Voltage CCA V .
