Product details

Temperature range and environment

The SN74AHCT1G32DCKR: Rated for -40°C to 85°C, this gate fits commercial and industrial environments — outdoor telecom cabinets, factory-floor control panels, and HVAC controllers are typical deployment spots. The SC-70-5 footprint is compact enough for dense PCB layouts where board area is tight.

Lifecycle and compliance

TI lists this part as Active with no end-of-life notice. ROHS3 compliant, so it clears EU and global environmental requirements without an exemption.

Frequently asked questions

Is SN74AHCT1G32DCKR RoHS compliant?

Yes, it is ROHS3 compliant — no exemptions needed. Suitable for EU and global markets with RoHS requirements.

What is the propagation delay of SN74AHCT1G32DCKR at 5V?

Maximum propagation delay is 7.9 ns at 5V with a 50 pF load. That covers the worst-case timing across temperature and supply variation.

What is the difference between SN74AHCT1G32 and SN74LVC1G32?

The SN74LVC1G32 operates from 1.65V to 5.5V and uses LVCMOS thresholds, while the SN74AHCT1G32 is a 4.5V to 5.5V part with TTL-compatible thresholds. If your system is 3.3V or mixed-voltage, the LVC variant is the better fit; for a pure 5V TTL environment, the AHCT part is the natural choice.
