This document is a detailed description of Analog Devices ADM3070E/ADM3071E/ADM3072E/ADM3073E/ADM3074E/ADM3075E/ADM3076E/ADM3077E/ADM3078E products. It introduces the features and characteristics of the products, such as ±15 kV ESD protection, half-duplex and full-duplex options, hot-swap input structure, low EMI, low power shutdown current, high-Z output, etc.
The ADM307xE family are 3.3 V, low‑power RS‑485/RS‑422 transceivers with +15 kV ESD protection, available in half‑ and full‑duplex versions. They support up to 256 nodes on a bus and include fail‑safe receiver inputs, hot‑swap capability, and low‑power shutdown.
Typical applications include power/energy metering, industrial control, lighting systems, telecommunications, security systems, and instrumentation. The document lists functional block diagrams, timing specifications for each data‑rate group, absolute maximum ratings, and an ordering guide with temperature‑range package options.
