Description
The FXMAR2102 is a high-performance configurable
dual-voltage-supply translator for bi-directional voltage
translation over a wide range of input and output
voltages levels. The FXMAR2102 also works in a push-
pull environment.
It is intended for use as a voltage translator between
I
2C-Bus compliant masters and slaves. Internal 10K
pull-up resistors are provided.
The device is designed so 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 1.65V to 5.5V. VCCA can equal VCCB from
1.65V to 5.5V. Either VCC can 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 automatic direction-
sense capability. Either port may sense an input signal
and transfer it as an output signal to the other port.
