Analog Devices ADM488A/ADM489A Datasheet Rev A
The ADM488A and ADM489A are low‑power, full‑duplex differential line transceivers that meet RS‑485 and RS‑422 standards. They operate from a single 5 V + 10 % supply and support up to 32 nodes on a bus, with features such as reduced slew rate, short‑circuit protection and thermal shutdown.
The document provides detailed electrical specifications, timing parameters, absolute maximum ratings, pin configurations for SOIC and MSOP packages, and an ordering guide for the various temperature‑rated part numbers.
