SN75HVD3082EDR 1/1 Transceiver Half RS-485
The SN75HVD3082EDR is a high-performance low-power half-duplex RS-485 transceiver manufactured by Texas Instruments, a global leader in semiconductor solutions for industrial, automotive, and communication systems. Classified under interface ICs (drivers, receivers, transceivers), this device is fully compliant with the TIA/EIA-485A standard, featuring a single driver and single receiver configuration optimized for reliable data transmission over long-distance twisted-pair cables. It supports a maximum data rate of 200 kbps, making it ideal for low-speed communication networks, while its 1/8 unit load capability allows up to 256 nodes on a single bus, enabling scalable multi-device connections. Key functional features include fail-safe receiver operation (ensuring stable output during bus open, short-circuit, or idle conditions), glitch-free power-up/power-down bus behavior, and a thermal shutdown protection mechanism that safeguards the device from damage in fault conditions.
Engineered for energy efficiency, the SN75HVD3082EDR transceiver operates with a typical supply current of 0.3 mA in active mode and an ultra-low 1 nA in shutdown mode, making it perfect for battery-powered or power-constrained applications. It functions within a wide supply voltage range of 4.5V to 5.5V (nominal 5V) and maintains reliable performance across a commercial temperature range of 0°C to 70°C. The transceiver offers an extended common-mode voltage range of -7V to 12V, ensuring robust communication in harsh electrical environments, while its bus pins provide ESD protection of up to 15kV for enhanced durability. Additional electrical characteristics include a maximum supply current of 900 µA, fault protection from -9V to 14V, and compatibility with industry-standard SN75176 footprints for easy design migration.
