Product details

Temperature range and industrial deployment

Rated for -40°C to 125°C, this gate handles factory-floor ambient near ovens, outdoor telecom cabinets in direct sun, and under-hood auxiliary logic where the ECU sees underhood soak-back. The 125°C ceiling is the junction temperature — derate the 8 mA output if ambient plus self-heating pushes toward that limit in a still-air enclosure.

Timing — 8.5 ns at 5V

Max propagation delay is 8.5 ns with a 5V supply driving 50 pF.

Quiescent draw and always-on circuits

Quiescent current maxes at 2 µA across the full voltage range. That makes this gate a candidate for battery-backed power-management logic or always-on supervisory circuits where every microamp counts.

Lifecycle and sourcing posture

TI lists this part as Active and ROHS3 compliant.

Frequently asked questions

What is the difference between SN74AHC02RGYR and SN74AHCT02RGYR?

The SN74AHCT02 variant uses TTL-compatible input thresholds (typically 0.8V low, 2.0V high) versus the AHC's CMOS thresholds (0.5V–1.65V low, 1.5V–3.85V high). If your driving device is a 5V TTL output, the AHCT version gives cleaner noise margin. For pure CMOS or 3.3V logic, the AHC version is the standard choice.

Does SN74AHC02RGYR have a cross-reference to other NOR gates?

No single-gate NOR direct cross is listed. The closest functional sibling in the 74AHC family is the single-gate NAND SN74AHC1G00DBVT or the single-gate OR SN74AHC1G32DCKT, but those are different logic functions. For a quad NOR replacement, look at the 74AHC02 in alternate packages (SOIC, TSSOP) rather than a different logic type.
