The Fairchild Semiconductor 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.

This Fairchild Semiconductor 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 voltage translation over the voltage ranges: 1.8V, 2.5V, 3.3V, 5.0V.

The Fairchild Semiconductor device remains in 3-state until both VCCs reach active levels allowing either VCC to be powered-up first. Internal power down control circuits place the device in 3-state if either VCC 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.

Features

  • 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 VCC level
  • Non-preferential power-up; either VCC may be powered-up first
  • Outputs remain in 3-state until active VCC level is reached
  • Outputs switch to 3-state if either VCC is at GND
  • Power-off high impedance
  • Active high output enable referenced to VCCA 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)
