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 voltage ranges 1.8V, 2.5V, 3.3V, and 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. Schmitt triggers are used on data inputs for signal noise suppression. Typically the inputs have 100 millivolts of hysteresis over the full VCC range. The FXM2IC102 typically consumes only 230nA during “no I2C data transactions” when VCCA = 1.8V and VCCB = 3.3V. See Figure 4 and Figure 5 for more details. FXM2IC102 exhibits robust I2C repeater performance due to strong current sinking capability in > 400pf bus segments. See Figure 6 and Figure 7 for details.

The FXM2IC102 is a configurable dual-voltage-supply translator designed for bi-directional voltage translation over a wide range of input and output voltage levels.

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 voltage ranges 1.8V, 2.5V, 3.3V, and 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.

Schmitt triggers are used on data inputs for signal noise suppression. Typically the inputs have 100 millivolts of hysteresis over the full VCC range.

The FXM2IC102 typically consumes only 230nA during “no I2C data transactions” when VCCA = 1.8V and VCCB = 3.3V. See Figure 4 and Figure 5 for more details.

FXM2IC102 exhibits robust I2C repeater performance due to strong current sinking capability in > 400pf bus segments. See Figure 6 and Figure 7 for details.
