The SN74AHCT1G04DBVR: The datasheet quotes 9ns max propagation delay at 5V with a 50pF load. The 8mA output drive (both source and sink) is standard for this family.
The part ships in a SOT-23-5 package. Surface-mount only — no through-hole variant exists. The 5-pin footprint is compact enough for dense boards but still inspectable under a microscope.
The SN74LVC1G04 is a 1.65V to 5.5V wide-range part with CMOS input thresholds, while the SN74AHCT1G04 is 4.5V to 5.5V only with TTL-compatible thresholds (0.8V low, 2V high). If your design runs on 3.3V or needs lower voltage operation, the LVC version is the right pick. For a 5V TTL-interfacing application, the AHCT is a direct fit.
A direct functional equivalent is any single-gate inverter in the 74AHCT family with the same SOT-23-5 footprint, such as the SN74AHCT1G04DCKR (same die, different tape/reel suffix). For a NOR gate alternative, the SN74AHCT1G02DCKR offers two inputs but the same supply and temperature range.
