Analog Devices ADM3483E/ADM3486E/ADM3488E/ADM3490E/ADM3491E RS-485/RS-422 Transceiver Datasheet
The ADM3483E, ADM3486E, ADM3488E, ADM3490E, and ADM3491E are 3.3 V, low‑power RS‑485/RS‑422 transceivers with up to +15 kV ESD protection. They support half‑duplex (ADM3483E, ADM3486E) or full‑duplex (ADM3488E, ADM3490E, ADM3491E) operation and are designed for balanced data transmission on multipoint bus lines.
Key features include a common‑mode input range of –7 V to +12 V, up to 32 nodes on a bus, thermal shutdown, short‑circuit protection, and availability in 8‑lead and 14‑lead narrow SOIC packages. Detailed driver and receiver timing specifications, pin configurations, and absolute maximum ratings are provided.
