SOIC-14 integration and supply rails
The SN74AHCT04D is a hex inverter in a 14-SOIC package (0.154" body width, 3.90 mm), surface-mount with a 1.27 mm pitch — a standard footprint that routes cleanly on two-layer boards without via congestion. Operating temperature covers -40 °C to 125 °C, qualifying the part for industrial enclosures and outdoor equipment where ambient swings exceed commercial-grade limits.
Output drive and timing margin
Input logic thresholds are 0.8 V low and 2 V high at 5 V supply — TTL-compatible levels that interface directly with 3.3 V logic outputs that swing above 2 V.
Fully ROHS3 compliant (no exemptions), so it passes EU material restrictions without a waiver. Quiescent current is 2 µA max, making it a low-overhead choice for power-sensitive boards where the logic block idles most of the time.
