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.  
The driver differential outputs and the receiver differential inputs are connected internally to for a bus port  
suitable for half-duplex (two-wire bus) communication. A cable invert pin (INV) allows active correction of  
mis-wires that may occur during installation. Upon detecting communication errors, the user can apply a logic  
HIGH to the INV pin, effectively inverting the polarity of the differential bus port, thereby correcting for the  
reversed bus wires.  
These devices feature a wide common-mode voltage range, making them suitable for multi-point applications  
over long cable runs. These devices are characterized from –40°C to 105°C.  
INV Input Can Correct  
for Crossed Wires  
VFAULT up to 70 V
