It belongs to TI's 74AUP family, the ultra-low-power logic series that draws nanoamp-level quiescent current at 0.8V to 3.6V supply. The 4mA output drive (both high and low) is modest — enough to drive a single CMOS load or a short trace, but not a terminated transmission line or multiple fan-outs. For bus applications, the 3-state output is the key feature: it lets the buffer disconnect from the bus when not selected, avoiding contention with other drivers. ## Package and temperature grade Housed in a 5-pin SOT-23-5 (SC-74A) package, the part fits a standard 0.95mm-pitch footprint common on small logic boards. The -40°C to 85°C operating range covers industrial control, telecom, and consumer equipment — but not extended automotive or military environments. Available in both Tape & Reel and Cut Tape options, the part is suited for both prototyping and production pick-and-place. The supply voltage spans 0.8V to 3.6V, making it compatible with 1.2V, 1.8V, 2.5V, and 3.3V logic families without a level translator. ## Lifecycle and compliance For new designs, this part is a safe choice in the 74AUP family. The low supply voltage and nanoamp standby current make it a natural fit for battery-powered or energy-harvesting systems where every microamp counts.","metaTitle":"TI SN74AUP1G126DBVR Buffer, Non-Inverting, 3-State, SOT-23-5","metaDescription":"Texas Instruments SN74AUP1G126DBVR single buffer with 3-state output, 0.8V-3.6V supply, 4mA drive.
