FXMAR2104UMX

The FXMAR2104 is a 4-bit high-performance, configurable dual-voltage supply, open-drain translator for bi-directional voltage translation over a wide range of input and output voltages levels. The FXMAR2104 also works in a push-pull environment. Intended for use as a voltage translator in applications using the I2C-Bus interface, the input and output voltage levels are compatible with I2C device specification voltage levels. Eight internal 10KO pull-up resistors are integrated. 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 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. Non-preferential power-up means 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.
