Product details

Quad 2-input NOR gate with Schmitt-trigger inputs for automotive and industrial logic

The wide supply range of 2V to 6V lets it work directly from 3.3V or 5V rails without external level shifters.

Rated for 2V to 6V, this gate accepts standard CMOS and TTL levels across its range. The low-level input threshold spans 1V to 3V, and the high-level threshold spans 1.5V to 4.2V, depending on supply. At 5V operation, the 12ns propagation delay (into 50pF load) is fast enough for most automotive sensor interfaces and control logic without needing a faster (and pricier) LVC or AHC family part.

Frequently asked questions

Does SN74HCS02QDRQ1 have Schmitt trigger inputs?

Yes, the SN74HCS02QDRQ1 features Schmitt-trigger inputs on all four NOR gates, providing hysteresis for noise rejection on slow or noisy input signals.

Is SN74HCS02QDRQ1 AEC-Q100 qualified?

Yes, the SN74HCS02QDRQ1 is part of the Automotive, AEC-Q100, 74HCS series and is qualified to AEC-Q100 automotive-grade standards.
