DESCRIPTION
This device is a half-duplex transceiver designed for
RS-485 data bus networks. Powered by a 5-V supply, it is
fully compliant with the TIA/EIA-485A standard. With
controlled output transition times, this device is suitable for
signaling rates up to 200 kbps over long twisted-pair
cables. The device is designed to operate with very low
supply current, typically less than 0.6 mA, exclusive of the
load. When in the inactive shutdown mode, the supply
current drops to a few nanoamps, making these devices
ideal for power-sensitive applications.
The wide common-mode range and high ESD protection
levels of these devices make them suitable for demanding
applications such as energy meter networks, electrical
inverters, status/command signals across telecom racks,
cabled chassis interconnects, and industrial automation
networks where noise tolerance is essential. The
SN65HVD3082E and SN75HVD3082E match the
industry-standard footprint of the SN75176. Power-on
reset circuits keep the outputs in a high-impedence state
until the supply voltage has stabilized. A thermal shutdown
function protects the device from damage due to system
fault conditions. The SN75HVD3082E is characterized for
operation from 0°C to 70°C and the SN65HVD3082E is
characterized for operation from −40°C to 85°C air
temperature.
