Texas Instruments  SN65HVD3082EPE4

The SNx5HVD308xE devices are half-duplex transceivers designed for RS-485 data busnetworks. Powered by a 5-V supply, they are fully compliant with TIA/EIA-485A standard. Withcontrolled transition times, these devices are suitable for transmitting data over longtwisted-pair cables. SN65HVD3082E and SN75HVD3082E devices are optimized for signaling rates up to200 kbps. The SN65HVD3085E device is suitable for data transmission up to 1 Mbps, whereas theSN65HVD3088E device is suitable for applications that require signaling rates up to
20 Mbps.

These devices are designed to operate with very low supply current, typically 0.3 mA,exclusive of the load. When in the inactive-shutdown mode, the supply current drops to a fewnanoamps, which makes these devices ideal for power-sensitive applications.

The wide common-mode range and high ESD-protection levels of these devices makes themsuitable for demanding applications such as energy meter networks, electrical inverters, status andcommand signals across telecom racks, cabled chassis interconnects, and industrial automationnetworks where noise tolerance is essential. These devices match the industry-standard footprint ofthe SN75176 device. Power-on-reset circuits keep the outputs in a high-impedance state until thesupply voltage has stabilized. A thermal-shutdown function protects the device from damage due tosystem fault conditions. The SN75HVD3082E is characterized for operation from 0°C to 70°C andSN65HVD308xE are characterized for operation from –40°C to 85°C air temperature. The D packageversion of the SN65HVD3082E has been characterized for operation from –40°C to 105°C.
