FXMAR2102 Overview
The FXMAR2102 is a high-performance configurable dual-voltage-supply translator for bi-directional voltage translation over a wide range of input and output voltages levels. The FXMAR2102 also works in a pushpull environment. It is intended for use as a voltage translator between I2C-Bus® pliant masters and slaves. Internal 10KΩ pull-up resistors are provided. The device is designed so 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 1.65V to 5.5V. VCCA can equal VCCB from 1.65V to 5.5V. 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 directionsense capability. Either port may sense an input signal and transfer it as an output signal to the other port....
