Frequently asked questions
Is SN74HC08QDRQ1 AEC-Q100 qualified?
Yes, the SN74HC08QDRQ1 is part of the Automotive, AEC-Q100 series, making it qualified for automotive applications including under-hood and cabin electronics.
Is SN74HC08QDRQ1 a direct replacement for SN74HC08D?
The SN74HC08QDRQ1 is the automotive-grade variant of the standard SN74HC08D. Both are quad 2-input AND gates in 14-SOIC with the same logic function and pinout, but the QDRQ1 suffix adds AEC-Q100 qualification and the extended -40°C to 125°C temperature range. It is a drop-in replacement for the commercial part in designs requiring automotive reliability.
When sourcing SN74HC08QDRQ1, what is the closest functional second-source?
The SN74LV08ADR is a pin-compatible quad 2-input AND gate in the same 14-SOIC package, but it uses 74LV logic with a lower supply voltage range (2V to 5.5V) and faster propagation delay (7.9ns at 5V). It is not automotive-qualified (commercial temperature only). For a true automotive-grade second source, stick with the 74HC family; the SN74LV08ADR is a functional alternate only if your design can tolerate the speed and voltage differences.
