Product details

Six Schmitt-trigger inverters for automotive and industrial signal conditioning

The SN74HCS14QDRQ1 contains six inverter gates with Schmitt-trigger inputs in a 14-SOIC package. It is part of the 74HCS family with AEC-Q100 qualification and operates from 2V to 6V over -40°C to 125°C.

Sourcing and lifecycle

The SN74HCS14QDRQ1 is listed as Active with ROHS3 compliance. For dual-sourcing resilience, the SN74HCS04PWR is a functional peer — same 74HCS series, same 6-channel inverter topology with Schmitt trigger, same supply range and temperature grade — but verify the pinout and logic polarity match your layout. The SN74HCU04PWT and SN74LVU04APWT are also hex inverters but lack the Schmitt trigger input.

Frequently asked questions

Is the SN74HCS14QDRQ1 automotive qualified?

Yes, it is AEC-Q100 qualified, part of the Automotive 74HCS series, and rated for -40°C to 125°C operation.

Does SN74HCS14QDRQ1 have Schmitt trigger inputs?

Yes, each of the six inverter channels has a Schmitt trigger input for noise immunity on slow or noisy signals.

What voltage does SN74HCS14QDRQ1 operate at?

The supply voltage range is 2V to 6V, covering both 3.3V and 5V logic rails.

Is SN74HCS14QDRQ1 a direct replacement for SN74HC14?

The SN74HCS14QDRQ1 is a newer automotive-grade evolution of the classic 74HC14 hex Schmitt inverter. Both are 14-SOIC, 6-channel, Schmitt-trigger inverters, but the HCS variant adds AEC-Q100 qualification and a wider temperature range. Verify the pinout matches your layout before substituting.

What is the pinout of SN74HCS14QDRQ1?

The device is in a standard 14-SOIC package (3.90 mm width). Pin 1 is the input of inverter 1, pin 2 its output, and so on through the six gates. VCC is pin 14, GND is pin 7. The datasheet provides the full pin diagram.
