ISL83485IBZ-T7A

ISL83485IBZ-T7A is a low power, high speed or slew rate limited, RS-485/RS-422 transceiver. This device is BiCMOS 3.3V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. It uses slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications. Data rates up to 10Mbps are achievable by using the ISL83485 which feature higher slew rates. Logic inputs accept signals in excess of 5.5V, making them compatible with 5V logic families. Receiver (Rx) inputs feature a “fail-safe if open” design, which ensures a logic high output if Rx inputs are floating. Application includes factory automation, security networks, building environmental control systems, industrial/process control networks, level translators, RS-232 “Extension Cords”.
