FXMA2102UMX General 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 in applications using the I²C bus interface, the input and output voltage levels are compatible with I²C device specification voltage levels. External pull-up resistors are required.The device is designed so that the A port tracks the V_CCA level and the B port tracks the V_CCB level. This allows for bi-directional A/B port voltage translation between any two levels from 1.65V to 5.5V. V_CCA can equal V_CCB from 1.65V to 5.5V. The OE pin is referenced to V_CCA.Either V_CC can be powered-up first. Internal power-down control circuits place the device in 3-state if either V_CC 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.
