Complementary outputs (Q and Q̅) give the firmware engineer the option to read the serial stream on either polarity, saving an inversion gate in the SPI or bit-bang routine. The -55°C to 125°C operating range covers industrial enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics without a temperature-grade upcharge. ## Package and board-fit for 16-SOIC layout Housed in a 16-SOIC narrow-body (3.90 mm body width), the CD74HC165M matches the JEDEC MS-012 footprint that is standard across the 74HC logic family. The tube packaging is typical for through-hole assembly or low-volume rework; for high-volume pick-and-place, order the tape-and-reel variant if the BOM quantity exceeds a few hundred units. ## Active lifecycle — no LTB pressure The ROHS3 compliance is current with EU Directive 2015/863, so the part passes restricted-substance audits without an exemption letter.","metaTitle":"CD74HC165M 8-bit shift register, 74HC, 2V-6V, -55/+125°C","metaDescription":"Texas Instruments CD74HC165M 8-bit parallel/serial shift register, 74HC logic family, 2V-6V supply, -55°C to 125°C, 16-SOIC.
