Overview
The FXMA2104UMX, produced by onsemi, is a 4-bit high-performance, configurable dual-voltage supply, open-drain translator designed for bi-directional voltage translation over a wide range of input and output voltage levels. This device is specifically intended for use in applications utilizing the I2C-Bus® interface, ensuring compatibility with I2C device specification voltage levels. External pull-up resistors are required for operation. The FXMA2104UMX features automatic direction-sense capability, allowing either port to sense an input signal and transfer it as an output signal to the other port. It supports non-preferential power-up, where either VCC can be powered-up first, and internal power-down control circuits place the device in 3-state if either VCC is removed.
