FEATURES  
DESCRIPTION  
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.

Bus-Pin ESD Protection Up to 15 kV  
1/2 Unit Load—Up to 64 Nodes on a Bus  
Bus Open Failsafe Receiver  
Available in Small MSOP-8 Package  
Meets or Exceeds the Requirements of the  
TIA/EIA−485A Standard

Industry-Standard SN75176 Footprint  
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.
