AEC-Q100 Grade 1 — under-hood temperature band
The 74HC4075D-Q100118: This temperature band covers under-hood and engine-bay locations where ambient soaks above 105°C on a hot day; Grade 1 qualification means the part passed the full reliability stress sequence (HTOL, TC, HAST, ESD) at that temperature without parametric drift. Capable is not qualified — this part carries the AEC-Q stamp.
Triple 3-input OR — logic function and timing
Three independent 3-input OR gates in a single 14-SOIC package. Propagation delay is 17ns max at 6V with a 50pF load — this sets the data-path timing budget; the output rise time into the actual load capacitance adds to the 17ns, so the effective toggle rate at the receiver will be lower than the reciprocal of 17ns suggests. Quiescent current is 2µA max, negligible for always-on modules in a vehicle.
Active production — sourcing for automotive BOMs
Lifecycle status is Active. For a BOM that carries this line, the AEC-Q100 traceability and PPAP documentation are available through the supply chain — the OEM auditor will expect to see the qualification data on file.
