Linear Technology 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.

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.

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. Pricing starts at $1.91 each in 1,000 piece quantities.
