Single buffer with an open-drain output for mixed-voltage rails
The SN74AUC1G07DBVR is a single non-inverting buffer from TI's 74AUC logic family, packing one buffer element in a five-pin SOT-23-5 package. The open-drain output is the key feature here — it lets you wire-AND multiple outputs on a shared pull-up rail, or level-shift a 0.8V logic signal up to a 2.7V bus without an external translator.
Supply range and drive capability
Runs on a 0.8V to 2.7V supply — that covers the sub-1V core voltages of modern MCUs and FPGAs, plus the 1.8V and 2.5V logic rails common in portable gear. The output sinks 9mA when low; the high side is open, so the pull-up resistor and the downstream input's threshold set the high-level voltage. At 0.8V supply the 9mA sink is still available, but the pull-up resistor must be sized to keep the output rise time within the bus timing budget.
Temperature grade and board-level fit
Rated for -40°C to 85°C ambient — the industrial temperature band. The SOT-23-5 footprint is a standard small-outline transistor package; the 0.95mm pin pitch and 2.9mm body length fit easily on two-layer boards with basic soldering iron rework. No exposed pad, so the thermal path is through the leads only — fine for the sub-10mW dissipation here.
Lifecycle and compliance status
TI lists the SN74AUC1G07DBVR as Active and ROHS3 Compliant. That means it's still in the catalog for new designs and ongoing production — no last-time-buy window to watch. The RoHS3 declaration covers the full substance restriction list including the four phthalates.
