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 push− pull environment. It is intended for use as a voltage translator between I2C−Bus pliant masters and slaves. Internal 10 kW 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 1.65 V to 5.5 V. VCCA can equal VCCB from 1.65 V to 5.5 V. 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.
