•
Designed for RS-485 and RS-422 Networks  
Failsafe Receiver for Open-Circuit,  
Short-Circuit and Idle-Bus Conditions  
DESCRIPTION  
These devices are designed to survive overvoltage faults such as direct shorts to power supplies, mis-wiring  
faults, connector failures, cable crushes, and tool mis-applications. They are also robust to ESD events, with high  
levels of protection to human-body model specifications.  
These devices combine a differential driver and a differential receiver, which operate from a single power supply.  
In the 'HVD1785, 'HVD1786, and 'HVD1787, the driver differential outputs and the receiver differential inputs are  
connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. In the 'HVD1791,  
the driver differential outputs and the receiver differential inputs are separate pins, to form a bus port suitable for  
full-duplex (four-wire bus) communication. These ports feature a wide common-mode voltage range, making the  
devices suitable for multipoint applications over long cable runs. These devices are characterized from –40°C to  
105°C.  
VFAULT up to 70 V
