The FXM2IC102 is a configurable dual-voltage-supply translator designed for bi-directional voltage translation over a wide range of input and output voltages levels.

The FXM2IC102 is intended for use as a voltage translator in applications using the I²C bus interface. Input and output voltage levels are compatible with I²C device specification voltage levels.

The device is 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 voltage translation over the voltage ranges: 1.8V, 2.5V, 3.3V, 5.0V.

The device remains in 3-state until both V_CCs reach active levels allowing either V_CC to be powered-up first. Internal power down control circuits place the device in 3-state if either V_CC is removed.

The two ports of the device have auto-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 from 1.65V to 5.5V
• Buffer isolates capacitance and allows 400pF on each port
• Open-drain inputs/outputs
• Accommodates Standard-mode and Fast-mode I² C-bus devices
• Fully configurable: Inputs and outputs track V_CC level
• Non-preferential power-up; either V_CC may be powered-up first
• Outputs remain in 3-state until active V_CC level is reached
• Outputs switch to 3-state if either V_CC is at GND
• Power-off high impedance
• Active high output enable referenced to V_CCA voltage
• 5V tolerant output enable
• Packaged in 8-terminal leadless MicroPak (1.6mm x 1.6mm)
• Direction control not needed
• ESD protection exceeds:
  
  • 8kV HBM ESD (per JESD22-A114 & Mil Std 883e 3015.7)
  • 15kV HBM I/O to GND ESD (per JESD22-A114 & Mil Std 883e 3015.7)
