The 85°C upper limit is the ambient, not the junction — in a 70°C enclosure with no forced air, the self-heating from the push-pull output driving a 50pF load at 20MHz adds roughly 10°C, keeping the die within the rated envelope. ROHS3 compliance covers the full substance restriction list including the four phthalates — no exemption declarations needed for EU-market equipment. No single-source risk — the 74HC logic family has multiple second-source vendors, though pin-compatible alternatives vary by package and temperature grade.","metaTitle":"SN74HC166DR Texas Instruments 8-Bit Shift Register, 2-6V","metaDescription":"SN74HC166DR 8-bit parallel/serial shift register, 2V-6V supply, -40°C to 85°C, 16-SOIC.
