Analog Devices ADM3483/ADM3485/ADM3488/ADM3490/ADM3491 Datasheet Rev E
The ADM3483/ADM3485/ADM3488/ADM3490/ADM3491 family are low‑power differential line transceivers that operate from a single 3.3 V supply. They support half‑duplex (ADM3483, ADM3485) or full‑duplex (ADM3488, ADM3490, ADM3491) communication for RS‑485 and RS‑422 applications such as industrial control, telecom and HVAC.
Key features include reduced slew‑rate drivers for low EMI, a shutdown mode with nano‑ampere current draw, and the ability to connect up to 32 transceivers on the same bus. The devices are offered in 8‑lead and 14‑lead SOIC packages and are RoHS compliant.
