Averting potential system damage
31 August 2010
Industry’s first cross-wire immunity transceiver for fail-safe installations.
Texas Instruments (TI) has introduced a new symmetric polarity transceiver that protects the system from communication losses and potential damage should the signal wires be inadvertently reversed during installation or maintenance.
The SN65HVD96, using TI’s patent-pending SymPol technology, provides high bus fault protection, making it desirable for harsh industrial environments where third-party installers often make the connections. The inverted bus wires are detected internally and corrected automatically, eliminating the need for intervention by the controller or operator without the need for firmware changes.
Applications that can benefit from this technology include heating, ventilating, and air conditioning (HVAC) equipment, surveillance cameras, surveillance IP network cameras, building automation, industrial lighting, and other industrial applications.
This device is designed to function alongside isolation devices such as TI’s ISO7241C. TI also provides IBIS models for the SN65HVD96, which designers can use for simulations.
The SN65HVD96 is available now in a SOIC (D) package with eight pins.
