This reference design provides a 500kbps 5V RS-485 interface using the SN65HVD22 extended common-mode RS-485 transceiver. The extended -20 V to 25 V Common-Mode Voltage Range, more than double the TIA/EIA-485 requirement, providing robust signal integrity and enabling use in long cable networks
Features
Wide common-mode range (-20V to 25V) enables use in long cable networks
More than 100mV receiver hysteresis - highly reliable in harsh environments
Low standby current: 1uA max
Failsafe receiver for open circuit, short circuit, and idle-bus conditions
Texas Instruments and Accelerated Designs, Inc. have collaborated together to provide TI customers with schematic symbols and PCB layout footprints for TI products.
Step 2: Download the Symbol and Footprint from the CAD.bxl file table.
Texas Instruments and Accelerated Designs, Inc. have collaborated together to provide TI customers with schematic symbols and PCB layout footprints for TI products.
Both PCB footprints and schematic symbols are available for download in a vendor neutral format, which can then be exported to the leading EDA CAD/CAE design tools using the Ultra Librarian Reader. The reader is available as a (free download.).
The UL Reader is a subset of the Ultra Librarian toolset that can generate, import, and export components and their attributes in virtually any EDA CAD/CAE format.
