The SN74F08N: Not rated for extended industrial or automotive ambient.
Output drive and logic thresholds
Output sourcing current is 1 mA high, 20 mA low — the high-level drive is weak, so a 74F output driving a long trace or a high-impedance load needs a pull-up resistor or a buffer if the fan-out exceeds a few TTL loads. Input logic-low threshold is 0.8V, high threshold is 2V — standard TTL-compatible levels. A 3.3V driver's output-high at 2.4V still registers as a logic high, but the noise margin is only 0.4V; keep the trace short and the ground plane clean if mixing voltage domains.
