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.

System GPIO Resources Not Required when OE Intended for use as a voltage translator in applications 2 Tied to V CCA using the I C-Bus interface, the input and output 2 2 voltage levels are compatible with IC device I C 400pF Buffer / Repeater specification voltage levels. External pull-up resistors 2 I C-Bus Isolation are required. A/B Port V = 175mV (Typical), V = 150mV, OL IL The device is designed so that the A port tracks the I = 6mA OL V level and the B port tracks the V level. This CCA CCB allows for bi-directional A/B port voltage translation Open-Drain Inputs / Outputs between any two levels from 1.65V to 5.5V. V can CCA Accommodates Standard-Mode and Fast-Mode equal V from 1.65V to 5.5V. CCB 2 I C-Bus Devices Non-preferential power-up means either V can be CC 2 Supports I C Clock Stretching & Multi-Master powered-up first. Internal power-down control circuits place the device in 3-state if either V is removed. Fully Configurable: Inputs and Outputs Track V CC 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 ESD (per JESD22-A114) - 2kV CDM (per JESD22-C101) Ordering Information Operating Top Packing Part Number Temperature Package Mark Method Range 5000 Units on FXMA2104UMX -40 to +85C BX 12-Lead, Ultrathin, MLP, 1.8mm x 1.8mm Tape and Reel 2011 Fairchild Semiconductor Corporation www.fairchildsemi.com FXMA2104 Rev. 1.0.1
