RS422/RS485 Transceivers Guaranteed over High Temperatures for Automotive Applications

(PresseBox) (Milpitas, CA, ) Linear Technology Corporation expands the RS422/RS485 transceiver product family with an "H-grade" option designed for high temperature applications. LTC285xH versions feature an extended operating temperature of
-40°C to 125°C, as well as the attributes traditionally required for these applications. The new temperature grade broadens Linear’s line of industry-standard low power CMOS transceivers, and helps ensure reliable data transmission in harsh environmental conditions commonly posed by automotive applications.

Linear offers a wide selection of LTC285xH transceivers. Select models feature slew rate limiting, while others include a receiving logic-selectable 120Ohm termination. All devices are designed to operate in systems with 3.3V or 5V supplies, possess a maximum data rate of 20Mbps and maintain a high input impedance capable of supporting up to 256 nodes. In addition, enhanced ESD protection guarantees that no damage or latchup can occur up to ±15kV HBM. These features, coupled with a wide operating window, make the LTC285xH family suitable for an array of automotive applications including level translation, backplane transceiving and low power RS422/RS485 transceiving.

The LTC285x family has a variety of ordering options. Aside from the H-grade version, "C" and "I" versions offer more relaxed operating temperature ranges, from 0°C to 70°C and -40°C to 85°C, respectively. Half-and full-duplex versions are available as well.

Industry-standard packages include an 8-lead 3mm x 3mm DFN, SO-8, MSOP-10 and SSOP-16, all of which are RoHS compliant. Now shipping in production volume LTC285xH transceivers complement Linear’s growing Interface product line. Visit www.linear.com for additional product selection and information.
