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 FXMAR2104 also works in a push-pull environment. Internal 10K Pull-Up Resistors Intended for use as a voltage translator in applications System GPIO Resources Not Required when OE 2 using the I C-Bus interface, the input and output Tied to V CCA 2 voltage levels are compatible with IC device 2 I C-Bus Isolation specification voltage levels. Eight internal 10K pull-up resistors are integrated. A/B Port V = 175mV (Typical), V = 150mV, OL IL I = 6mA OL The device is designed so that the A port tracks the V level and the B port tracks the V level. This Open-Drain Inputs / Outputs CCA CCB allows for bi-directional A/B port voltage translation Works in a Push-Pull Environment between any two levels from 1.65V to 5.5V. V can CCA equal V from 1.65V to 5.5V. Accommodates Standard-Mode and Fast-Mode CCB 2 I C-Bus Devices Non-preferential power-up means V can be powered- CC 2 up first. Internal power-down control circuits place the Supports I C Clock Stretching & Multi-Master device in 3-state if either V is removed. CC Fully Configurable: Inputs and Outputs Track V CC The two ports of the device have automatic direction- Non-Preferential Power-Up Either V May Be CC sense capability. Either port may sense an input signal Powered-Up First and transfer it as an output signal to the other port. Outputs Switch to 3-State if Either V is at GND CC Tolerant Output Enable: 5V Packaged in 12-Lead Ultrathin MLP (1.8mm x 1.8mm) ESD Protection Exceeds: - 5kV HBM (per JESD22-A114) - 2kV CDM (per JESD22-C101) Ordering Information Operating Top Packing Part Number Package Temperature Range Mark Method 5000 Units on FXMAR2104UMX -40 to +85C BY 12-Lead, Ultrathin MLP, 1.8mm x 1.8mm Tape and Reel 2011 Fairchild Semiconductor Corporation www.fairchildsemi.com FXMAR2104 Rev. 1.0.1
