These devices are half-duplex transceivers designed for RS-485 data busnetworks. Powered by a 5-V supply, they are fully compliant with TIA/EIA-485Astandard. With controlled transition times, these devices are suitable fortransmitting data over long twisted-pair cables. SN65HVD3082E and SN75HVD3082Edevices are optimized for signaling rates up to 200 kbps. SN65HVD3085E issuitable for data transmission up to 1 Mbps, whereas SN65HVD3088E is suitablefor applications requiring signaling rates up to 20 Mbps. These devices aredesigned to operate with very low supply current, typically 0.3 mA, exclusive ofthe load. When in the inactive shutdown mode, the supply current drops to a fewnanoamps, making these devices ideal for power-sensitive applications.
The wide common-mode range and high ESD protection levels of these devicesmake them suitable for demanding applications such as energy meter networks,electrical inverters, status/command signals across telecom racks, cabledchassis interconnects, and industrial automation networks where noise toleranceis essential. These devices match the industry-standard footprint of SN75176.Power-on reset circuits keep the outputs in a high impedance state until thesupply voltage has stabilized. A thermal shutdown function protects the devicefrom damage due to system fault conditions. The SN75HVD3082E is characterizedfor operation from 0°C to 70°C and SN65HVD308xE are characterized for operationfrom -40°C to 85°C air temperature.
