Single OR gate in the 74AUP ultra-low-power family
The Texas Instruments SN74AUP1G32DCKT is a single 2-input OR gate from the 74AUP series, designed for ultra-low-power and low-voltage logic applications. It operates from a supply voltage of 0.8 V to 3.6 V, making it suitable for battery-powered and portable devices where power budgets are tight. The gate draws a maximum quiescent current of 500 nA, and can source or sink 4 mA on each output. Propagation delay is 6.4 ns at 3.3 V with a 30 pF load, fast enough for most general-purpose logic and level-translation tasks.
SC-70-5 footprint — what the board sees
The SN74AUP1G32DCKT is supplied in a 5-lead SC-70-5 package (also known as SOT-353). This is a small, surface-mount package with a 1.25 mm body width and 0.65 mm lead pitch. The supplier device package is SC-70-5. For rework, standard hot-air profiles for SOT-353 apply; no special bake is required if the moisture barrier bag has been sealed (MSL 1 per TI's standard for this package family).
Supply range and temperature grade
The wide supply range (0.8 V to 3.6 V) allows direct interfacing with 1.8 V, 2.5 V, and 3.3 V logic families without external level shifters. The input logic levels are specified as low: 0.7 V to 0.9 V, and high: 1.6 V to 2 V, which are compatible with standard CMOS thresholds across the supply range. The operating temperature range is -40°C to 85°C, covering industrial and commercial environments but not automotive under-hood or extended-temperature applications.
Lifecycle and compliance
It is ROHS3 compliant, with no known end-of-life notices.
