Product details

Single NOR gate in a 5V logic path

The SN74AHCT1G02DBVR is a single 2-input NOR gate from the 74AHCT family, in a SOT-23-5 package. The 7.5 ns propagation delay at 5 V with a 50 pF load sets the timing floor for a 5 V logic path — fast enough for most glue-logic and bus-interface roles without the shoot-through current of a faster AC family.

Supply rail and logic thresholds

The input low threshold is 0.8 V and the high threshold is 2 V, which means it interprets a standard 5 V CMOS or TTL output correctly but may not see a 3.3 V signal as a valid high without a level shifter. Quiescent current maxes at 1 µA, so it adds negligible draw to a 5 V rail.

Active production, SOT-23-5 footprint

The SOT-23-5 (SC-74A) footprint is a standard small-outline transistor package — the same land pattern as many single-gate logic parts, so it drops into existing layouts without a pad revision.

Frequently asked questions

When sourcing SN74AHCT1G02DBVR, what is the closest functional second-source?

The SN74AHC1G00DBVT is a single 2-input NAND gate from the 74AHC series in the same SOT-23-5 package. It shares the same 8 mA output drive and 7.5 ns propagation delay at 5 V, but its supply range is 2 V to 5.5 V and its logic thresholds are lower. It is a pin-compatible swap only if the logic function (NAND vs NOR) and threshold levels match the application.
