The FXMA2102 is a high-performance configurable dual-voltage power supply converter that enables bidirectional voltage translation over a wide range of input and output voltage levels. Used as a voltage translator in applications using the I2C bus interface, the input and output voltage levels comply with the I2C device specified voltage levels. An external pull-up resistor is required. The device is designed so that the A port can track the VCCA level and the B port can track the VCCB level. This enables bidirectional A/B port voltage translation between any two levels from 1.65V to 5.5V. VCCA can be equal to VCCB from 1.65V to 5.5V. The OE pin is referenced to VCCA. Either VCC can be powered up first. If either VCC is removed, an internal power-down control circuit places the device in 3-state. Both ports of the device feature automatic orientation sensing. Either port can sense an input signal and pass it on to the other port as an output signal.
