This PDF document is about the introduction of ADM4850-ADM4857 series products, including product features, characteristics, application scenarios, etc.
The ADM4850‑ADM4857 family are differential line transceivers for high‑speed half‑ and full‑duplex RS‑485/RS‑422 communication. They feature reduced slew‑rate for low EMI, true fail‑safe receiver inputs, and can support up to 256 devices on a single bus.
The document includes detailed electrical specifications, timing characteristics, absolute maximum ratings, pin‑out diagrams, test circuits, and an ordering guide for the various 8‑lead SOIC and LFCSP packages.
