DESCRIPTION/ORDERING INFORMATION
This 2-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. This device is fully specified for partial-power-down applications using I off . The I off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package.

Description
The TXB0102 device is a 2-bit noninverting translator that uses two separate configurablepower-supply rails. The A port is designed to track VCCA.VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designedto track VCCB. VCCB accepts any supply voltage from1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA must notexceed VCCB.
When the output-enable (OE) input is low, all outputs are placed in the high-impedancestate.
This device is fully specified for partial-power-down applications usingIoff. The Ioff circuitry disables the outputs whenthe device is powered down. This inhibits current backflow into the device which prevents damage tothe device.
OE must be tied to GND through a pulldown resistor to assure the high-impedance stateduring power up or power down; the minimum value of the resistor is determined by thecurrent-sourcing capability of the driver.
NanoFree? technology is a major breakthrough in IC packaging concepts, using the die asthe package.
