FXMAx21 Dual-Supply Voltage Translators

onsemi FXMAx21 Dual-Supply Translators are high performance, configurable dual-voltage supply for bi-directional voltage translation over a wide range of input and output voltage levels. onsemi FXMA2104 is a 4-bit device that includes an I²C buffer/repeater and isolator and is intended for open-drain applications. The FXMAR2104 is a 4-bit device that includes an I²C isolator and is intended for open-drain and push-pull applications. The FXMAR2102 is a 2-bit device that includes an I²C isolator and is designed for I²C applications. Each of these devices are 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 1.65V to 5.5V.
