Single AND gate for sub-3V logic rails
The SN74AUC1G08DBVR is a single 2-input AND gate from Texas Instruments' 74AUC series, designed for ultra-low-voltage operation from 0.8V to 2.7V. This makes it a natural fit for battery-powered or core-logic domains where the supply rail sits below 2.5V — think IoT endpoints, portable instruments, or SoC companion logic that must track a 1.2V or 1.8V bus.
Propagation delay and drive capability
Maximum propagation delay is 2ns at 2.5V with a 30pF load, so the gate keeps up with fast control signals in a 200+ MHz data path without adding a clock-cycle penalty. Output drive is symmetrical at 9mA source and sink — enough to switch a downstream flip-flop clock input or a small MOSFET gate through a series resistor, but not intended for heavy fan-out beyond four or five standard CMOS loads. Quiescent current maxes at 10 µA, meaning the gate's own draw is negligible in a sleep-mode budget — relevant when the AND function must remain powered to gate a wake-up signal while the rest of the system is off.
Package and footprint
Housed in the SOT-23-5 package (SC-74A body), the SN74AUC1G08DBVR occupies about 3mm² of board area. The 5-pin footprint is standard — no hidden thermal pad, no exposed paddle. It routes easily on a two-layer board; the 0.95mm pin pitch keeps the escape traces wide enough for 6-mil design rules without micro-vias.
