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 I
and output voltage levels are compatible with I
specification voltage levels.
The device is designed so that the A port tracks the
V
allows for bi-directional voltage translation over voltage
ranges: 1.8V, 2.5V, 3.3V, 5.0V.
The device remains in 3-state until both V

Internal power-down control circuits place the device in
3-state if either V
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.
