TXB0106PWR

This 6- 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. The TXB0106 is designed so that the OE input circuit is supplied by VCCA. This device is fully specified for partial- power- down applications using Ioff. The Ioff 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.
