This input hysteresis rejects slow edges and noise on the gate inputs, making the part suitable for signal conditioning in automotive and industrial control modules where ground bounce or long traces degrade signal integrity. ## Automotive qualification and wide-temperature coverage Qualified to AEC-Q100, the part is specified across the full automotive temperature range of -40°C to 125°C. This covers under-hood and cabin electronics where ambient temperatures exceed the commercial 85°C limit. The 2V to 6V supply range allows direct interfacing with both 3.3V and 5V logic families without external level translation, simplifying BOM consolidation in mixed-voltage designs. ## Package and thermal considerations for the layout Supplied in a 14-WFQFN with exposed pad (3x2.5 mm body), the package footprint matches the standard 14-pin WQFN land pattern. The exposed pad must be soldered to a thermal via array on the PCB to achieve the rated thermal performance, particularly in high-ambient automotive environments. Propagation delay is 12 ns maximum at 6V supply with a 50 pF load, placing the gate in the mid-speed range of the 74HC logic family. The 7.8 mA symmetric output drive handles standard CMOS fan-out loads without additional buffering.","metaTitle":"SN74HCS02QBQARQ1 Texas Instruments NOR Gate, 4-Ch 2-Input","metaDescription":"SN74HCS02QBQARQ1 TI 74HC NOR gate, 4 circuits, 2 inputs, Schmitt trigger, 2V-6V supply, -40°C to 125°C, AEC-Q100.
