Description

General part information

FXMAR2104 Series

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 10KΩ pull-up resistors are integrated.The device is designed so that the A port tracks the VCCAlevel and the B port tracks the VCCBlevel. This allows for bi-directional A/B port voltage translation between any two levels from 1.65V to 5.5V. VCCAcan equal VCCBfrom 1.65V to 5.5V.Non-preferential power-up means VCCcan be powered-up first. Internal power-down control circuits place the device in 3-state if either VCCis 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.
