Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This Texas Instruments datasheet covers the SN65HVD3082E, SN75HVD3082E, SN65HVD3085E, and SH65HVD3088E half-duplex RS-485 transceivers. Designed for low-power industrial automation and energy metering networks, these devices meet TIA/EIA-485A standards with ESD protection up to 15kV. Key parameters include a supply voltage of 4.5–5.5V, quiescent current as low as 0.3mA in active mode, and signaling rates ranging from 0.2 Mbps to 20 Mbps depending on the specific part number. Available in an MSOP-8 package, they feature failsafe receivers and glitch-free power-up/down bus inputs.
