1. Description

This 6-bit noninverting translator uses two separateconfigurable power-supply rails. The A port isdesigned to track VccA· VccA accepts any supplyvoltage from 1.2 V to 3.6 V. The B port is designed totrack VccB. VccB accepts any supply voltage from1 .65 V to 5.5 V. This allows for universal low-voltagebidirectional translation between any of the 1.2 V, 1.5V. 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes. VccAshould not exceed VccBWhen the output- enable (OE) input is low, all outputsare placed in the high-impedance state.The TXB0106 is designed so that the OE input circuitis supplied by VccA. This device is fully specified for partial-power-downapplications using loff. The loff circuitry disables theoutputs, preventing damaging current backflowthrough the device when it is powered down. To ensure the high-impedance state during power upor power down, OE should be tied to GND through apulldown resistor; the minimum value of the resistor isdetermined by the current-sourcing capability of thedriver.
