What this dual buffer does on your board
The SN74AUP2G07DCKR is a dual non-inverting buffer with open-drain outputs from TI's 74AUP series, designed for ultra-low-power logic-level translation and line driving in battery-operated or low-voltage systems. Each of the two elements handles one bit, and the open-drain output means the buffer can only sink current — the pull-up resistor to the target rail sets the high-level voltage, making this part a natural fit for level shifting between different supply domains.
Supply range and drive capability
The supply voltage spans 0.8V to 3.6V, covering the full low-voltage logic spectrum from 1.2V to 3.3V rails, and the buffer sinks 4mA on the low side — enough to drive a standard LED or a downstream logic input with a 1kΩ pull-up. Because the output is open drain, the high-level voltage is set by the pull-up resistor's supply, not by VCC — so you can interface a 1.8V microcontroller to a 3.3V peripheral without a dedicated level translator IC.
Package and footprint for layout
Housed in a 6-pin SC-70 (SOT-363) package, the SN74AUP2G07DCKR occupies minimal board area — about 2.0 mm × 2.1 mm — and the 0.65 mm pin pitch is easily routable on a two-layer board. The supplier device package is SC-70-6, and the part is offered in Tape & Reel (TR) or Cut Tape (CT) options for prototyping or production reels.
Lifecycle and compliance
The part is RoHS3 compliant, and the operating temperature range of -40°C to 85°C covers industrial and commercial environments.
