What the AEC-Q100 grade buys your BOM
The SN74HC00QPWRG4Q1 is a Texas Instruments quad 2-input NAND gate from the Automotive 74HC series, carrying AEC-Q100 qualification. For a BOM destined for under-hood, engine-bay, or outdoor telecom, this is the difference between a gate that holds its logic thresholds and one that drifts out of spec on a hot day.
Supply voltage and logic compatibility
The supply range is 2V to 6V, which covers both 5V and 3.3V logic families without external level shifters in many mixed-voltage designs. The input logic low threshold is 0.5V to 1.8V, and the high threshold is 1.5V to 4.2V, so a 3.3V CMOS output will reliably drive the high input, and a 5V TTL output will be recognised as a valid low. The output can sink or source 5.2 mA per channel, enough to drive a downstream CMOS load or a small LED indicator.
Lifecycle and sourcing posture
Texas Instruments lists it as ROHS3 compliant. Sourcing is quoted per RFQ against the BOM quantity; no stock-holding claim is made here.
Package and footprint fit
The 14-TSSOP package (4.40 mm width, 0.65 mm pitch) is a common footprint shared with many standard 74HC00 devices. The 0.65 mm pitch is manageable on a two-layer board with careful routing, though a four-layer stack-up simplifies fan-out if the gate is surrounded by dense logic. The surface-mount package is compatible with standard reflow profiles.
