ADM1491EBRZ-REEL7 Description

Short technical summary and product information.

The ADM1491EBRZ-REEL7 is a full-duplex RS-485/RS-422 transceiver designed for high-speed motor control applications. It supports data rates up to 16 Mbps and provides ±8 kV ESD protection on the RS-485 I/O pins. The device complies with ANSI/TIA/EIA-485-A-1998 and features open circuit fail-safe, thermal shutdown protection, and can drive up to 32 nodes on the bus. It operates from a 4.75V to 5.25V supply voltage and is specified over the -40°C to +85°C temperature range. The transceiver is available in a 14-lead SOIC package (14-SOIC) for surface mount assembly. Typical applications include RS-485/RS-422 interfaces, industrial field networks, high data rate motor control, multipoint data transmission systems, and single-ended-to-differential signal conversion.
