SN74AUP Ultra-Low-Power Logic Variants
Texas Instruments SN74AUP devices are ultra-low-power single, dual, and small logic ICs for compact low-voltage systems operating down to sub-1 V class rails on selected variants.
Ultra-low-power point-of-use logic for compact boards
Compare SN74AUP gates, inverters, buffers, translators, packages, drive current, and voltage limits.
The SN74AUP family is designed for very low-power logic functions placed close to processors, sensors, and small digital interfaces. It focuses on single-gate and small-channel devices such as NAND, NOR, inverter, buffer, translator, and simple control logic in tiny SOT, SC, SON, USON, X2SON, DSBGA, and VSSOP packages. Many variants support very low supply voltages, making the family useful in battery-operated and always-on sections of a product.
SN74AUP differs from broader LVC or AHC families because it prioritizes low current and small footprint over high output drive. It is a strong choice for local signal inversion, enable-line conditioning, reset gating, level-domain housekeeping, and lightweight interface glue. Selection should verify minimum supply voltage, input tolerance, output drive, propagation delay, leakage, and package assembly capability, especially for X2SON or DSBGA devices.

How to Choose the Right SN74AUP Buffers, Drivers, Receivers and Transceivers
Use for local low-power logic
AUP is strongest when the signal load is light and current budget matters.
Do not overdrive outputs
Check output current and capacitive load; choose LVC or AHC when stronger drive is needed.
Validate assembly package
X2SON, USON, and DSBGA packages need suitable PCB fabrication, placement, and inspection capability.
