SN65HVD82D Robust RS-485 Transceiver

Texas Instruments' device features robust drivers and receivers for demanding industrial applications

Image of Texas Instruments' SN65HVD82D Robust RS-485 TransceiverTexas Instruments' SN65HVD82D comes equipped with robust drivers and receivers for demanding industrial applications. The bus pins are robust to ESD events, with high levels of protection for human-body model, air-gap discharge, and contact discharge specifications. The device combines a differential driver and a differential receiver, which operate from a single 5 V power supply. The driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. The device features a wide common-mode voltage range making the device suitable for multi-point applications over long cable runs.
