Low power RS-485 / RS-422 differential bus transceiver.
The LMS485E is a low‑power differential bus transceiver designed for high‑speed bidirectional data communication on multipoint RS‑485/RS‑422 lines. It meets ANSI TIA/EIA RS‑422‑B, RS‑485‑A, ITU V.11 and X.27 standards and includes +15 kV ESD protection on driver outputs and receiver inputs.
Key features include a single 5 V supply, low quiescent current, thermal shutdown and short‑circuit protection, and availability in 8‑pin SOIC and 8‑pin DIP packages. The device supports up to 32 transceivers on a bus and offers fail‑safe biasing for noisy environments.
