The TXB0102 device is a 2-bit noninverting translator that 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 must not
When the output-enable (OE) input is low, all outputs are placed in the high-impedance
This device is fully specified for partial-power-down applications using
Ioff. The Ioff circuitry disables the outputs when
the device is powered down. This inhibits current backflow into the device which prevents damage to
OE must be tied to GND through a pulldown resistor to assure the high-impedance state
during power up or power down; the minimum value of the resistor is determined by the
current-sourcing capability of the driver.
NanoFree™ technology is a major breakthrough in IC packaging concepts, using the die as
