The FXM2IC102 is intended for use as a voltage translator in applications using the I2C bus interface. Input and output voltage levels are compatible with I2C device specification voltage levels. 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 voltage translation over the voltage ranges: 1.8V, 2.5V, 3.3V, 5.0V. The device remains in 3-state until both VCCs reach active levels allowing either VCC to 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 auto-direction sense capability. Either port may sense an input signal and transfer it as an output signal to the other port. 1.65V to 5.5V Buffer isolates capacitance and allows 400pF on each port Open-drain inputs/outputs Accommodates Standard-mode and Fast-mode I2C-bus devices...
