Overview
Description
ADM3486EARZ is an Analog Devices RS-485/RS-422 transceiver. It provides a two‑wire, half‑duplex differential interface that lets a microcontroller communicate on a multi‑drop RS‑485/RS‑422 bus. The device includes transmitter and receiver with a fail‑safe receiver, 3‑state enable control, and is designed for low power operation. Packaged in an 8‑pin package, the EARZ suffix indicates RoHS‑compliant, lead‑free packaging (often with tape & reel). Common applications include industrial automation, building management, and other long‑distance serial links requiring robust differential signaling. For exact electrical specs and timing, consult the ADM3486 datasheet.
