Analog Devices ADM488/ADM489 Datasheet Rev D
The ADM488 and ADM489 are low‑power, full‑duplex differential line transceivers that meet EIA RS‑485 and RS‑422 standards. They operate from a single 5 V ±10 % supply and include features such as reduced slew rate, short‑circuit protection, and high electromagnetic immunity.
The devices are available in PDIP, SOIC, and TSSOP packages and support up to 32 transceivers on a single bus. Detailed specifications, timing diagrams, pin configurations, and test circuits are provided for designers.
