Product details

Quad OR gate with Schmitt-trigger inputs — rated for the automotive temperature span

The Texas Instruments SN74HCS32QDRQ1 is a quad 2-input OR gate from the 74HCS logic family, featuring Schmitt-trigger inputs on all four gates. It operates from a 2V to 6V supply and is specified across the full automotive temperature range of -40°C to 125°C. Outputs source and sink 7.8 mA each, enough to drive a downstream gate input or a small LED indicator directly. The 14-SOIC package (3.90 mm body width) is a standard logic footprint that fits existing PCB layouts without a board spin.

Frequently asked questions

Is SN74HCS32QDRQ1 AEC-Q100 qualified?

Yes, the SN74HCS32QDRQ1 is AEC-Q100 qualified and belongs to TI's Automotive, AEC-Q100, 74HCS series. It is rated for the -40°C to 125°C temperature range, suitable for automotive under-hood and industrial environments.

What is the closest functional equivalent to SN74HCS32QDRQ1?

A functional equivalent within the same automotive 74HCS family is the SN74HCS14QDRQ1, which is a hex inverter with Schmitt-trigger inputs. It shares the same supply range, temperature grade, and package footprint, but provides inverting logic instead of OR gates. For a non-automotive OR gate, the SN74AC32DR offers higher output drive (24 mA) but only commercial temperature range.
