MAXIM MAX481E/MAX483E/MAX485E/MAX487E MAX491E/MAX1487E ±15kV ESD-Protected Slew-Rate-Limited Low-Power RS-485/RS-422 Transceivers handbook
The Maxim MAX481E, MAX483E, MAX485E, MAX487E–MAX491E and MAX1487E family provides low‑power RS‑485/RS‑422 transceivers designed for harsh environments. Each device includes a driver and a receiver, ±15 kV ESD protection, and operates from a single +5 V supply.
The series offers both slew‑rate‑limited (up to 250 kbps) and unrestricted‑slew‑rate (up to 2.5 Mbps) versions, low‑current shutdown modes, short‑circuit current limiting, and fail‑safe receiver inputs. Detailed electrical characteristics, pin descriptions, and test methods are provided for system designers.
