SN74AUP1G240

具有三态输出的低功耗单路缓冲器/驱动器

The AUP family is ’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.

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 ensure 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 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.
