FXM2IC102
Dual Supply 2-Bit I2C Interface Voltage Translator with
Configurable Voltage Supplies and Signal Levels and
Auto Direction Sensing
Features
Bi-directional interface between any two levels from
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
Fully configurable: Inputs and outputs track VCC level
Non-preferential power-up; either VCC may be
powered-up first
Outputs remain in 3-state until active VCC level is
reached
Outputs switch to 3-state if either VCC is at GND
Power off high impedance
Active high output enable referenced to VCCA voltage
5V tolerant output enable
Packaged in 8-terminal leadless MicroPak
(1.6mm x 1.6mm)
Direction control not needed
ESD protection exceeds:
– 8kV HBM ESD
(per JESD22-A114 & Mil Std 883e 3015.7)
– 15kV HBM I/O to GND ESD
(per JESD22-A114 & Mil Std 883e 3015.7)
General Description
The FXM2IC102 is a configurable dual-voltage-supply
translator designed for bi-directional voltage translation
over a wide range of input and output voltages levels.
The FXM2IC102 is intended for use as a voltage trans-
lator 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.

Application Notes
The FXM2IC102 has open-drain outputs and requires pull-up resistors on the four data I/O pins as shown in the above
figure. If a pair of data I/O pins (An/Bn) are not used, they both should be tied to Gnd (or both to VCC). In this case,
pull-down or pull-up resistors are not required.
The recommended values for the pull-up resistors (RPU) are 1kminimum to 10kmaximum. The recommended
value for the bypass capacitors (CBP) is 1.1µF. The recommended value for the pull-down resistor (RPD) on OE is 1k
or higher and may depend upon the current-sinking capability of the device driving the OE pin.
