The FXM2IC102 is intended for use as a voltage trans- lator in applications using the I C bus interface. Input and output voltage levels are compatible with I C 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 The device remains in 3-state until both V CC s 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.

This benefit derives from the chip design. When either V CC is at 0V, outputs are in a high-impedance state. The control input (OE) is designed to track the V CCA supply. A pull-down resistor tying OE to GND should be used to ensure that bus con- tention, 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. The recommended power-up sequence is the following: 1. Apply power to the first V CC 2. Apply power to the second V CC 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 V CC 3. Remove power from other V CC Number Name Description CCA A Side Power Supply 2, 3 A , A A Side Inputs or 3-State Outputs

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Note: 1. I O Absolute Maximum Rating must be observed. Recommended Operating Conditions (2) The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings. Note: 2. All unused inputs and I/O pins must be held at V CCI or GND.

If a pair of data I/O pins (A n n ) are not used, they both should be tied to Gnd (or both to V CC ). In this case, pull-down or pull-up resistors are not required. The recommended values for the pull-up resistors (R PU ) are 1k Ω minimum to 10k Ω maximum. The recommended value for the bypass capacitors (C BP ) is 1.1µF. The recommended value for the pull-down resistor (R PD ) on OE is 1k Ω or higher and may depend upon the current-sinking capability of the device driving the OE pin.
