Low-voltage single-gate buffer for battery-powered logic
The Texas Instruments SN74AUP1G34DRYR is a single-gate non-inverting buffer from the 74AUP series, designed for ultra-low-power logic chains operating from 0.8V to 3.6V supply rails. The push-pull output delivers 4mA source and sink at the rated voltage, which is sufficient to drive a single CMOS load or a short PCB trace without external buffering. Housed in a 6-UFDFN package (6-SON, 1.45x1 mm body), the part occupies minimal board area and suits space-constrained designs like wearables, sensor nodes, or handheld instruments where every square millimeter counts.
Supply voltage range and output drive — what they mean for fit
At the low end, the 4mA output drive is derated but still adequate for a 1.8V logic input; at 3.3V the full 4mA is available, which is within the input leakage budget of most downstream CMOS gates. Because the output is push-pull (not open-drain or 3-state), it actively drives both high and low levels without requiring an external pull-up resistor. This simplifies the BOM and saves a passive component, but the part cannot be used on a shared bus where multiple outputs must be tri-stated — for that, a 3-state buffer like the SN74LVC1G125YZPR would be the correct choice.
