Texas Instruments' two-bit non-inverting translator is a bidirectional voltage-level translator and can be used to establish digital switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails, with the A ports supporting operating voltages from 1.65 V to 3.6 V while it tracks the V_CCA supply, and the B ports supporting operating voltages from 2.3 V to 5.5 V while it tracks the V_CCB supply.
