00 — Overview

What the SN65HVD3082 does

The SN65HVD308xE family comprises low-power RS-485 transceivers available in MSOP-8 packages. These half-duplex devices support signaling rates from 0.2 Mbps up to 20 Mbps, featuring a 5-V supply range, 15-kV ESD protection, and quiescent currents as low as 1 nA in shutdown mode. Optimized for long twisted-pair cable transmission, they serve energy meter networks, motor control systems, and industrial automation. The series includes variants for commercial, industrial, and military temperature grades, matching the industry-standard SN75176 footprint while providing failsafe receiver protection and glitch-free power-up/down bus inputs.
