This document introduces the characteristics and features of the ADM3483E/ADM3486E/ADM3488E/ADM3490E/ADM3491E series 3.3 V, ±15 kV ESD-Protected, Half- and Full-Duplex, RS-485/RS-422 Transceivers products.
The ADM3483E‑ADM3491E family are 3.3 V, low‑power RS‑485/RS‑422 transceivers with up to +15 kV ESD protection. They support half‑ and full‑duplex operation, up to 32 nodes on a bus, and include shutdown and short‑circuit protection. The devices are offered in 8‑lead and 14‑lead narrow SOIC packages.
The datasheet provides electrical specifications such as data‑rate limits, common‑mode input range, supply voltage, and pin configurations. Functional block diagrams, timing parameters, and absolute maximum ratings are also included for design reference.
