Supply voltage and speed — the 74AUC edge
The SN74AUC1G32DBVR is a single 2-input OR gate from Texas Instruments' 74AUC series, operating from 0.8 V to 2.7 V — this sub-1 V floor is the key differentiator versus the 74LVC or 74HC families, which bottom out at 1.65 V and 2 V respectively. At 2.5 V with a 30 pF load, the maximum propagation delay is 2.1 ns, making it suitable for high-speed data paths in battery-powered portable equipment where the core voltage rail is dropping toward 1 V.
Package and footprint
Housed in a 5-pin SOT-23-5 (SC-74A) surface-mount package, the footprint is a standard 2.9 mm × 1.6 mm with 0.95 mm pin pitch — a direct drop-in for any single-gate logic position on a mixed-voltage board. The supply range from 0.8 V to 2.7 V means this gate can be powered from a 1.2 V or 1.8 V core rail without a separate regulator, saving a board component and simplifying the power tree.
Output drive and quiescent draw
Each output sources or sinks 9 mA — enough to drive a single CMOS load or a short PCB trace, but not intended for LED or relay coil drive without a buffer. Quiescent current maxes at 10 µA, so the gate's own power draw is negligible in a battery-powered system where the MCU may sleep at microamps.
Lifecycle and compliance
Operating temperature covers -40°C to 85°C, the industrial range, so it fits outdoor telecom, automotive cabin, and factory-floor control boards.
