This device has robust drivers and receivers for demanding industrial applications. The bus pins are robust to ESD events, with high levels of protection to Human-Body Model, Air-Gap Discharge, and Contact Discharge specifications.
The device combines a differential driver and a differential receiver, which operate from a single 5-V 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. The device features a wide common-mode voltage range making the device suitable for multi-point applications over long cable runs. The device is characterized from –40°C to 85°C.

The SN65HVD72EVM evaluation module (EVM) helps you evaluate device performance, supporting fast development and analysis of data transmission systems using the SN65HVD72, SN65HVD75 and SN65HVD78 transceivers. The EVM board comes with the SN65HVD75 (20 Mbps) device soldered to the board. (...)
This design demonstrates the implementation of a buspowered RS-485 application and allows to evaluate different filters for the DC power. This saves the cost and space for a separate power wiring.
A new preferred approach by using On-off key modulation to transmit RS-485 signals over power line is (...)
The TIDA-00730 is an reference design examining how to protect an RS-485 bus against leathal transient waveforms such as IEC ESD, IEC EFT, and IEC surge. The reference design shows the level of protection that can be achieved through the implementation of a TVS diode on the bus lines of a standard (...)
The TIDA-00731 is a reference design examining how to protect an RS-485 bus against lethal transient waveforms such as IEC ESD, IEC EFT, and IEC surge. The reference design shows the level of protection that can be achieved through the implementation of an external protection scheme on the bus (...)
