TI has unveiled the highest-performance 3.3-V RS485 transceivers with IEC electrostatic discharge protection available in speed grades up to 50 Mbps. The 250-kbps SN65HVD72, 20-Mbps SN65HVD75 and 50-Mbps SN65HVD78 perform better than the competition across all key performance areas, including power, ESD and hysteresis, offering a tailored solution for designers using RS485 transceivers in harsh, noisy industrial applications.

To further enhance design, the devices feature a wide common-mode voltage range suitable for multi-point applications over long cable runs.

Key features and benefits of the SN65HVD72, SN65HVD75 and SN65HVD78

• Reliable in high-noise environments: With +/- 15 kV human body model (HBM) protection and +/- 12 kV IEC61000-4-2 contact and air-gap discharge, the SN65HVD7x family provides a 50 percent higher level of ESD protection over the competition for industrial applications.

• Power savings: Low quiescent supply current of less than 1 mA reduces system power meets the requirements of low-power applications, such as security cameras, DVRs, home automation and metering.

• Highest immunity to noise signals on the bus lines: Receiver hysteresis at least two times higher than the competition at 80 mV helps ensure signal integrity in noisy environments.

• Extended temperature range for industrial applications: SN65HVD7x devices are characterized from -40°C to 125°C.
