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, which produces very low undershoot and overshoot characteristics. The SN74AUP1G57 features configurable multiple functions. The output state is determined by eight patterns of 3-bit input. The user can choose the logic functions AND, OR, NAND, NOR, XNOR, inverter, and noninverter. All inputs can be connected to VCC or GND. The device functions as an independent gate with Schmitt-trigger inputs, which allow for slow input transition and better switching noise immunity at the input. 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. 8.2 Functional Block Diagram 8.3 Feature Description This part is available in the TI NanoStar package. It has low static-power consumption with ICC = 0.9 μA maximum and low dynamic power consumption (Cpd = 4.3 pF, Typical at 3.3 V). The inputs have low capacitance, with typical Ci = 1.5 pF. This part has low noise, with overshoot and undershoot less than 10% of VCC. This part supports partial-power-down mode operation. When this part is powered down (VCC = 0 V), the leakage current into the device is characterized by Ioff. Schmitt-trigger inputs provide hysterisis and consistency in VIH / VIL. It has a wide operating VCC range of 0.8 V to 3.6 V, and has been optimized for 3.3-V operation. 3.6-V I/O tolerant to support mixed-mode signal operation. It has a low propagation delay of 5.3 ns at 3.3 V. It is suitable for point-to-point applications. 8.4 Device Functional Modes Table 1 lists all the functional modes of the SN74AUP1G57. Table 1.
