FXMA2102 Overview
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 plaint 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.
