FXMA2102UMX

FXMA2102UMX is a dual supply, 2-bit voltage translator/buffer/repeater/isolator for I²C applications. It is a high-performance configurable dual-voltage-supply translator for bi-directional voltage translation over a wide range of input and output voltage levels. 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. The OE pin is referenced to VCCA. Either VCC can be powered up first. Internal power-down control circuits place the device in a 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.

• Bi-directional interface between any two levels range from 1.65V to 5.5V
• Direction control not needed
• System GPIO resources not required when OE Tied to VCCA
• I²C 400pF buffer / repeater, I²C bus isolation
• Open-Drain Inputs / Outputs, accommodates Standard-Mode and Fast-Mode I²C-Bus Devices
• Supports I²C clock stretching
• Fully Configurable: Inputs and Outputs Track VCC, Control Input (OE) Referenced to VCCA
• Non-Preferential Power-Up; Either VCC May Be Powered-Up First
• Outputs Switch to 3-State if Either VCC is at GND
• 8 lead MLP package, operating temperature range from -40 to +85°C
