SN75176  
DESCRIPTION  
This device is designed to survive overvoltage faults such as direct shorts to power supplies, mis-wiring faults,  
connector failures, cable crushes, and tool mis-applications. The internal current-limit circuits allow fault  
survivability without causing the high bus currents that otherwise might damage external components or power  
supplies. It is also robust to ESD events, with high levels of protection to the JEDEC or IEC human-body-model  
specification.  
This device combines 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 form a bus port  
suitable for half-duplex (two-wire bus) communication. This port features a wide common-mode voltage range,  
making the devices suitable for multipoint applications over long cable runs. This device is characterized from  
–40°C to 125°C. The SN65HVD1781 is pin-compatible with the industry-standard SN75176 transceiver, making it  
a drop-in upgrade for most devices.  
The HVD1781 is fully compliant with ANSI TIA/EIA 485-A with a 5-V supply and can operate with a 3.3-V supply  
with reduced driver output voltage for low-power applications.  
VFAULT up to 70 V
