These devices extend the RS-485 portfolio with a family of full-duplex transceivers with robust 3.3-V drivers and receivers and high levels of ESD protection. The ESD protection includes > ±30-kV HBM and > ±12-kV IEC61000-4-2 contact discharge. The large receiver hysteresis of the SN65HVD7x devices provides immunity to conducted differential noise and the wide operating temperature enables reliability in harsh operating environments. The SN65HVD7x devices are offered in a standard SOIC package as well as in a small-footprint MSOP package.
These devices each combine a differential driver and a differential receiver, which operate from a single 3.3-V power supply. Each driver and receiver has separate input and output pins for full-duplex bus communication designs. These devices all feature a wide common-mode voltage range which makes the devices suitable for multi-point applications over long cable runs.
The SN65HVD71, SN65HVD74, and SN65HVD77 devices are fully enabled with no external enabling pins.
The SN65HVD70, SN65HVD73, and SN65HVD76 devices have active-high driver enables and active-low receiver enables. A low, less than 5-µA standby current can be achieved by disabling both the driver and receiver.
These devices are characterized from –40°C to 125°C.
