The Texas Instruments SN74HCS4075QPWRQ1 is a triple 3-input OR gate from the Automotive 74HCS series, qualified to AEC-Q100 and rated for -40°C to 125°C ambient. Each of the three independent gates has Schmitt-trigger inputs, which clean up slow or noisy edges — useful when the input comes from a switch, a sensor with a long trace, or another logic family with different thresholds. The supply range spans 2V to 6V, so it can run off a 3.3V or 5V rail without a separate regulator.
12 ns propagation delay — timing budget for a 5V rail
Max propagation delay is 12 ns at 6V with a 50 pF load. At 5V it will be a few nanoseconds slower, but still fast enough for most automotive CAN, LIN, or sensor interface glue logic running below 20 MHz. The 2 µA quiescent current means it won't drain the battery in an always-on module.
Active, AEC-Q100, ROHS3 — sourcing reality
It is ROHS3 compliant and carries full AEC-Q100 automotive qualification.
14-TSSOP — footprint and rework
Housed in a 14-TSSOP (4.40 mm wide, 0.173" pitch), surface-mount. No thermal pad, so no via-stitch worry.
Tape and reel or cut tape — assembly line ready
Available in Tape & Reel (TR) for pick-and-place or Cut Tape (CT) for prototype runs. The Q suffix in the order code indicates the automotive-grade qualification, not the packaging format — both TR and CT options carry the same AEC-Q100 rating.
