SN65HVD3082EDR – 1Mbps Half-Duplex RS-485 Transceiver IC (SOIC-8)

Description

The SN65HVD3082EDR is a high-performance, low-power RS-485 transceiver designed for data communication in industrial applications. It is optimized to operate on a 3.3V power supply while maintaining high levels of signal integrity. This transceiver is fully compliant with the TIA/EIA-485 standard and is capable of data rates up to 1 Mbps, making it suitable for a wide range of serial networking tasks.

Engineered for robustness, the SN65HVD3082E features a high input impedance, allowing up to 256 nodes to be connected on a single bus without signal degradation. It also includes advanced protection features such as bus fault protection, thermal shutdown, and receiver fail-safe functionality, which ensures the output remains at a defined logic level even if the bus is open, shorted, or idle. The device comes in a compact SOIC-8 (SMD) package, ideal for modern space-constrained PCB designs.

Note: You may notice “VP3082” printed on the IC; please be assured that this is the correct marking for this component and its functionality remains identical to the SN65HVD3082EDR.
