LISTED UNDER:

RS-432 and RS-485 Transceivers Offer Linear Technology expanded its RS-422/RS-485 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 characteristics traditionally required for these applications. The new temperature grade is intended to ensure reliable data transmission in harsh environmental conditions commonly posed by automotive applications. Select LTC285xH transceiver models feature slew rate limiting, while others include a receiving logic-selectable 120-Ohm termination. All devices are designed to operate in systems with 3.3V or 5V supplies, possess a maximum data rate of 20 Mbps 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, according to the company. These features, coupled with a wide operating window, make the LTC285xH family appropriate for automotive applications including level translation, backplane transceiving and low power RS422/RS485 transceiving. 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 pricing starts at $1.91 each in 1,000-piece quantities.
