Technical details

Active production — single-gate OR in a compact footprint

The SN74AHCT1G32DRLR: Housed in a SOT-553 package (supplier device package SOT-5), the part occupies minimal board area — roughly 1.6 mm × 1.6 mm — making it a fit for dense, space-constrained designs where a single gate is needed without wasting a quad package.

Supply voltage and temperature grade

Input logic thresholds are 0.8V low and 2V high, so the gate accepts 3.3V signals as a valid high — useful for mixed-voltage interfaces without an external level shifter.

Propagation delay and quiescent draw

Maximum propagation delay is 7.9 ns at 5V with a 50 pF load — fast enough for most 5V logic chains running below 50 MHz. The 1 µA max quiescent current keeps the power budget tight in always-on or battery-backed sections.
