The AUP family is TI’s premier solution to the industry’s low-power needs in battery-powered portable applications. This family ensures a very low static and dynamic power consumption across the entire V_CC range of 0.8 V to 3.6 V, resulting in an increased battery life. This product also maintains excellent signal integrity (see Figure 1 and Figure 2).

The SN74AUP2G125 is a dual bus buffer gate designed for 0.8-V to 3.6-V V_CC operation. This device features dual line drivers with 3-state outputs. Each output is disabled when the corresponding output-enable (OE) input is high. This device has the input-disable feature, which allows floating input signals.

To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
