THVD1520DR TI RS-485 Transceiver | 8-SOIC | 5V, 250kbps, Half-Duplex

Product Overview

The THVD1520DR from Texas Instruments is a robust RS-485 transceiver designed for industrial communication networks. It operates from a single 5V supply and supports half-duplex data rates up to 250 kbps. The device features a 1/8 unit load, allowing up to 256 nodes on a single bus. With integrated ESD protection up to ±30 kV (HBM) and a wide common-mode range of -7V to +12V, it ensures reliable operation in harsh environments. The 8-SOIC package is compact and suitable for space-constrained applications.
