Description 

The FXMA2102 is a high−performance configurable dual−voltage−supply translator for bi−directional voltage translation over a wide range of input and output voltages levels. Intended for use as a voltage translator between I2C−Bus complaint masters and slaves. The device is designed so that the A port tracks the VCCA level and the B port tracks the VCCB level. This allows for bi−directional A/B port voltage translation between any two levels from 1.65 V to 5.5 V. VCCA can equal VCCB from 1.65 V to 5.5 V. The OE pin is referenced to VCCA. Either VCC can be powered−up first. Internal power−down control circuits place the device in 3−state if either VCC is removed. The two ports of the device have automatic direction sense capability. Either port may sense an input signal and transfer it as an output signal to the other port.
