Description
The FXMA2102 is a high-performance configurable
dual-voltage-supply translator for bi-directional voltage
translation over a wide range of input and output
voltages levels.
Intended for use as a voltage translator between I²C-
Bus^® complaint masters and slaves.
The device is designed so that the A port tracks the
V_CCA level and the B port tracks the V_CCB level. This
allows for bi-directional A/B port voltage translation
between any two levels from 1.65 V to 5.5 V. V_CCA can
equal V_CCB from 1.65V to 5.5V. The OE pin is
referenced to V_CCA.
Either V_CC can be powered-up first. Internal power-down
control circuits place the device in 3-state if either V_CC 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.
