DESCRIPTION/ORDERING INFORMATION
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 VCC 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 SN74AUP2G126 is a dual bus driver/line driver with 3-state outputs, designed for 0.8-V to 3.6-V VCC
operation. The outputs are disabled when the associated output-enable (OE) input is low. 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 GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
NanoStar™ package technology is a major breakthrough in IC packaging concepts, using the die as the
package.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
