The SN65HVD485E 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. This
device is suitable for data transmission up to 10 Mbps over
long twisted-pair cables and is designed to operate with
very low supply current, typically less than 2 mA, exclusive
of the load. When in the inactive shutdown mode, the
supply current drops below 1 mA.
The wide common-mode range and high ESD protection
levels of this device make it suitable for demanding
applications such as, electrical inverters, status/command
signals across telecom racks, cabled chassis
interconnects, and industrial automation networks where
noise tolerance is essential. The SN65HVD485E matches
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 SN65HVD485E is characterized for
operation from −40°C to 85°C air temperature.
