The SN65HVD08 and SN75HVD08 are RS-485 transceivers from TI with wide supply voltage range, low quiescent current and 1/8th unit load
The SN75HVD08 and SN65HVD08 are differential line drivers and receivers designed for balanced data transmission over RS‑485 networks. They operate from a 3 V to 5.5 V supply, consume less than 90 mW quiescent power, and provide 1/8 unit‑load capability for up to 256 nodes. Features include bus‑pin ESD protection exceeding 16 kV HBM, driver output slew‑rate limiting for 10 Mbps signal quality, and compatibility with ANSI TIA/EIA‑485 standards.
The datasheet details electrical characteristics, recommended operating conditions, absolute maximum ratings, and package options (SOIC and PDIP). It also includes mechanical dimensions, ordering information, and an important notice about warranty and product availability.
