This datasheet introduces the features of the ADM483E data transceiver, including ESD protection, data rate, supply voltage, common voltage range, node count, supply current, shutdown current, application scenarios, etc.
The ADM483E is a 5 V, low‑power data transceiver designed for half‑duplex RS‑485/RS‑422 communication on multipoint bus systems. It offers ±15 kV ESD protection, a shutdown current of only 0.1 µA, and fail‑safe receiver operation, making it suitable for electrically harsh environments.
Typical applications include low‑power RS‑485 networks, DTE‑DCE interfaces, and industrial LANs where up to 32 transceivers share a common bus. The device is supplied in an 8‑lead SOIC package and operates over an industrial temperature range of –40 °C to +85 °C.
