FXM2IC102 Dual Supply 2-Bit I2C Interface Voltage Translator with Configurable Voltage Supplies and Signal Levels and Auto Direction Sensing Features General Description ■ Bi-directional interface between any two levels from 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. ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ 1.65V to 5.5V Buffer isolates capacitance and allows 400pF on each port Open-drain inputs/outputs Accommodates Standard-mode and Fast-mode I2C-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) 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 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 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.

This benefit derives from the chip design. When either VCC is at 0V, outputs are in a high-impedance state. The control input (OE) is designed to track the VCCA supply. A pull-down resistor tying OE to GND should be used to ensure that bus contention, excessive currents, or oscillations do not occur during power-up/power-down. The size of the pull-down resistor is based upon the current-sinking capability of the device driving the OE pin. 1. Apply power to the first VCC. 2. Apply power to the second VCC. 3. Drive the OE input high to enable the device. The recommended power-down sequence is the following: 1. Drive OE input low to disable the device. 2. Remove power from either VCC. 3. Remove power from other VCC. ©2008 Fairchild Semiconductor Corporation FXM2IC102 Rev. 1.0.0 www.fairchildsemi.com 2 FXM2IC102 — Dual Supply 2-Bit I2C Interface Voltage Translator with Configurable Voltage Supplies and Signal Levels and Auto Direction Sensing Connection Diagram Stresses exceeding the absolute maximum ratings may damage the device.

If a pair of data I/O pins (An/Bn) are not used, they both should be tied to Gnd (or both to VCC). In this case, pull-down or pull-up resistors are not required. The recommended values for the pull-up resistors (RPU) are 1kΩ minimum to 10kΩ maximum. The recommended value for the bypass capacitors (CBP) is 1.1µF. The recommended value for the pull-down resistor (RPD) on OE is 1kΩ or higher and may depend upon the current-sinking capability of the device driving the OE pin. ©2008 Fairchild Semiconductor Corporation FXM2IC102 Rev. 1.0.0 www.fairchildsemi.com 4 FXM2IC102 — Dual Supply 2-Bit I2C Interface Voltage Translator with Configurable Voltage Supplies and Signal Levels and Auto Direction Sensing FXM2IC102 Application Circuit Symbol VIHA VCCA (V) VCCB (V) High Level Input Voltage 1.65–5.5 1.65–5.5 Data Inputs An 0.7 x VCCA 1.65–5.5 1.65–5.5 Control Input OE 0.9 x VCCA 1.65–5.5 1.65–5.5 Data Inputs Bn 0.7 x VCCB Low Level Input Voltage 1.65–5.5 1.65–5.5 Data Inputs An 0.3 x VCCA Parameter VIHB VILA VILB VOLA (3) Low Level Output Voltage VOLB(3) 0.1 x VCCA 0.3 x VCCB V 1.65–2.3 1.65–5.5 A Port IOL = 3mA 0.1 x VCCA V 3.0–5.5 1.65–5.5 IOL = 6mA 0.2 IOL = 3mA 0.1 x VCCB IOL = 6mA 0.2 1.65–5.5 1.65–2.3 1.65–5.5 3.0–5.5 0 Quiescent Supply Current ICCB Quiescent Supply Current V Control Input OE Power Off Leakage Current ICCA V Data Inputs Bn IOFF Quiescent Supply Current V 1.65–5.5 1.65–5.5 ICCZ(5) Units 1.65–5.5 1.65–5.5 ICCA/B(5)(6) Quiescent Supply Current Max. 1.65–5.5 Input Leakage Current 3-State Output Leakage Min. 1.65–5.5 II IOZ(4) Conditions B Port V Control input OE, VI = VCCA or GND ±1.0 µA 5.5 An VI or VO = 0V to 5.5V ±2.0 µA 5.5 0 Bn VI or VO = 0V to 5.5V ±2.0 5.5 5.5 A n , Bn VO = 0V to 5.5V, OE = VIL ±2.0 5.5 0 An VO = 0V to 5.5V, OE = Don’t Care ±2.0 0 5.5 Bn VO = 0V to 5.5V, OE = Don’t Care ±2.0 1.65–5.5 1.65–5.5 VI = VCCI or GND, IO = 0 5.0 µA 1.65–5.5 1.65–5.5 VI = VCCI or GND, IO = 0, OE = VIL 5.0 µA 0 1.65–5.5 µA 0 VI = 5.5V or GND, IO = 0, OE = Don’t Care, Bn to An –2.0 1.65–5.5 VI = 5.5V or GND, IO = 0, OE = Don’t Care, An to Bn –2.0 1.65–5.5 0 0 1.65–5.5 µA 2.0 µA 2.0 Notes: 3.
