What this single-gate inverter brings to a 0.8V-2.7V rail
The SN74AUC1GU04DCKR is a single unbuffered inverter from TI's 74AUC family, designed for the sub-2.7V supply world where every nanosecond of propagation delay and every microamp of quiescent current matters on a tightly regulated core rail. The 2.1ns max propagation delay at 2.5V with a 30pF load means this gate keeps up with high-speed clock distribution or signal cleanup in a 200+ MHz path without adding a full clock period of skew.
The 0.8V to 2.7V supply window covers the common 1.2V, 1.5V, 1.8V, and 2.5V logic rails. At the low end, 0.8V is below the threshold of many older 1.8V families, so verify your upstream driver's VOH meets the VIH of this inverter at the actual operating voltage. Output drive is symmetrical at 9mA source and 9mA sink at the rated supply — enough to switch a single standard load or a short PCB trace, but not intended to fan out to multiple CMOS inputs without checking the total capacitive load against the propagation delay derating.
Package, temperature grade, and compliance
Housed in the SC-70-5 (SOT-353) package, the 5-lead footprint is a common pinout for single-gate logic — the same pad layout used by many 1G-series parts from TI and competitors, which simplifies second-sourcing on the same PCB.
