DescriptionThis 4-bit non-inverting translator uses twoseparate configurable power-supply rails. The A port is designed to trackVCCA. VCCA accepts any supply voltage from 0.9 V to3.6 V. The B port is designed to track VCCB. VCCBaccepts any supply voltage from 0.9 V to 3.6 V. This allows for low Voltage bidirectional translation between 1 V, 1.2 V, 1.5V, 1.8 V, 2.5 V and 3.3 V voltage nodes. For the TXB0304, when the output-enable (OE) input is low,all outputs are placed in the high-impedance state. To ensure the high-impedance state during powerup or power down, OE should be tied to GND through a pull-down resistor; the minimum value of theresistor is determined by the current-sourcing capability of the driver. The OE device control pininput circuit is supplied by VCCA. This device is fully specified forpartial-power-down applications using Ioff. The Ioffcircuitry disables the outputs, preventing damaging current backflow through the device when it ispowered down. The only difference between TXB0304RSVR and TXBN0304 is the OE signal being active highand active low respectively.
