SN65HVD3085EDGKR

The SN65HVD3085EDGKR from Texas Instruments is a half-duplex transceiver engineered for RS-485 data bus networks. It operates from a 4.5V to 5.5V supply and is compliant with the TIA/EIA-485A standard. This transceiver is suitable for data transmission up to 1 Mbps and features controlled transition times for reliable performance over long twisted-pair cables.

Designed for power-sensitive applications, the SN65HVD3085EDGKR consumes very low supply current, typically 0.3 mA in active mode and dropping to 1 nA in shutdown mode. It supports up to 256 nodes on a bus with a 1/8 unit load. The device offers a wide common-mode range of -7V to 12V and features bus-pin ESD protection up to 15 kV. Fail-safe receiver functionality is included for bus open, bus shorted, and bus idle conditions, along with glitch-free power-up and power-down behavior.

This transceiver is characterized for operation from -40°C to 85°C. It is available in an 8-VSSOP package, with a surface mount type. The SN65HVD3085EDGKR is ideal for demanding applications such as energy meter networks, motor control, power inverters, industrial automation, and telecommunications equipment where noise tolerance and low power consumption are essential.
