Texas Instruments Inc. launches the 250kbps SN65HVD72, 20Mbit/s SN65HVD75 and 50Mbit/s SN65HVD78 transceivers with IEC ESD protection in speed grades up to 50Mbit/s.

Aside from ESD, the SN65HVD7x transceivers claim to perform better than competitive products in terms of power and hysteresis, particularly for harsh, noisy industrial applications. The devices also feature a wide common-mode voltage range suitable for multi-point applications over long cable runs.

For reliability in high-noise environments, the transceivers offer ±15kV human body model (HBM) protection and ±12 kV IEC61000-4-2 contact and air-gap discharge. They offer power savings because they use <1mA quiescent supply current. Also, they claim the highest immunity to noise signals on the bus lines, that is, receiver hysteresis is said to be at least two times higher than the competition at 80mV, ensuring signal integrity in noisy environments.

The SN65HVD72EVM evaluation module is available to support fast development and analysis of data transmission systems using the SN65HVD72, SN65HVD75 and SN65HVD78 transceivers, along with an IBIS model. It can be ordered today for Rs.2,722.22 ($49).

The SN65HVD72, SN65HVD75 and SN65HVD78 transceivers are characterized from -40°C to 125°C. They are available now in an 8-pin SOIC package. MSOP package options will be available in Q4 12. Suggested retail pricing is Rs.55.56 ($1) in 1,000-unit quantities for the SOIC package.
