Single inverter for mixed-voltage sensor interfaces
The SN74AHC1GU04DCKR is a single unbuffered inverter from the 74AHC family, operating from 2V to 5.5V. It accepts one input and delivers a complementary output with 8 mA source and sink capability at the rails. Maximum quiescent current is 1 µA, making it suitable for always-on sensor conditioning where standby power must stay below a few microamps.
7 ns propagation delay at 5V — timing budget for 50 pF loads
Maximum propagation delay is 7 ns at 5V supply with a 50 pF load. This sets the signal path latency for a single gate. Input logic thresholds scale with supply: low level is 0.3V to 1.1V, high level is 1.7V to 4.4V. At 3.3V operation, a 1.8V logic-high from a low-voltage sensor is still above the 1.7V threshold, so the inverter recognizes it correctly.
Active production — no obsolescence risk
The part is offered in Tape & Reel and Cut Tape options, and the SC-70-5 package (also known as SOT-353) is a standard footprint with broad second-source availability from other logic suppliers. ROHS3 compliance is confirmed, so it passes EU material restrictions without exemption paperwork.
