3.3-V RS485 transceivers target industrial apps

Designed for industrial applications, Texas Instruments Inc. has introduced high performance 3.3-V RS485 transceivers with IEC electrostatic discharge (ESD) protection available in speed grades up to 50 Mbps.

The 250-kbps SN65HVD72, 20-Mbps SN65HVD75 and 50-Mbps SN65HVD78 provide a 50 percent higher level of ESD protection over the competition with ±15 kV human body model (HBM) protection and ±12 kV IEC61000-4-2 contact and air-gap discharge, according to TI.

The devices also deliver low quiescent supply current of less than 1 mA, reducing system power for industrial applications, such as security cameras, DVRs, home automation and metering. Receiver hysteresis is at least two times higher than the competition at 80 mV, helping to ensure signal integrity in noisy environments, according to TI. SN65HVD7x devices are characterized from -40°C to 125°C.

Tools and Support

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 US$49. 

Availability, packaging and pricing

The SN65HVD72, SN65HVD75 and SN65HVD78 devices are available now in an 8-pin SOIC package. MSOP package options will be available in 4Q2012. Suggested retail pricing is US$1.00 in 1,000-unit quantities for the SOIC package.
