TEXAS INSTRUMENTS TXS0102DCTR

The TXS0102DCTR is a 2-bit Bidirectional Voltage-level Shifter suitable for use with the open-drain and push-pull application. It 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 to 3.6V while it tracks the VCCA supply and the B ports supporting operating voltages from 2.3 to 5.5V while it tracks the VCCB supply. This allows the support of both lower and higher logic signal levels while providing bidirectional translation capabilities between voltage nodes. When the output-enable (OE) input is low, all I/Os are placed in the high-impedance state, which significantly reduces the power-supply quiescent current consumption. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull-down resistor and the minimum value of the resistor is determined by the current-sourcing capability of driver.
