The RD74VT1G126 has a bus buffer gate with 3-state output in a 6 pin package. Output is disabled when the associated output enable (OE) input is low. To ensure the high impedance state during power up or power down, OE should be connected to GND through a pull-down resistor; the minimum value of the resistor is determined by the current sourcing capability of the driver. The input is designed to track VCCIN, which accepts voltages from 1.2V to 3.6V, and the output is designed to track VCCOUT, which operates at 1.2V to 3.6V. Low voltage and high-speed operation
