The AUP family is TIs premier solution to the industrys low power needs in
battery-powered portable applications. This family assures 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
AUP – The Lowest-Power Family ).
This buffer/driver is a single line driver with a 3-state output. The output is disabled
when the output-enable (OE) input is high. This device has the input-disable
feature, which allows floating input signals.
To assure the high-impedance state during power up or power down,
OE should be tied to VCC through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the
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 when
the device is powered down. This inhibits current backflow into the device which prevents damage to
