Product details

Supply range and logic-level compatibility

With a supply spanning 2V to 5.5V, this inverter works on 3.3V and 5V rails equally well. The input logic thresholds scale with supply: low-level threshold is 0.5V to 1.65V, high-level is 1.5V to 3.85V, so it cleanly interprets standard CMOS and TTL signals across the voltage range.

Propagation delay and output drive

Maximum propagation delay is 7.5ns at 5V with a 50pF load, fast enough for sensor readout gating, reset inversion, or clock buffering in automotive control modules.

It is ROHS3 compliant.

Frequently asked questions

Is SN74AHC1G04QDCKRQ1 AEC-Q100 qualified?

Yes, it is part of the Automotive, AEC-Q100 series, qualified for automotive-grade applications.

Is SN74AHC1G04QDCKRQ1 compatible with 3.3V logic?

Yes, the 2V to 5.5V supply range covers 3.3V operation, and the input logic thresholds are scaled for reliable 3.3V CMOS signaling.

Is SN74AHC1G04QDCKRQ1 a direct replacement for 74AHC1G04DCKR?

The SN74AHC1G04QDCKRQ1 is the automotive-qualified (AEC-Q100) version of the standard 74AHC1G04DCKR. Electrically identical, but the Q-suffix adds the extended temperature range and qualification for automotive use.
