Intersil has announced two high-speed, isolated RS-485 differential bus transceivers that provide 40Mbps bidirectional data communication for Industrial Internet of Things (IIoT) networks. The higher working voltage and reinforced isolation is required for today's medical and motor control applications.
The ISL3274xE transceivers provide low radiated emission and EMI susceptibility, support for up to 160 devices on the bus and a 125°C temperature range. These devices utilize giant magnetoresistance (GMR) technology that provides galvanic isolation to keep the communication bus free from common-mode noise generated in electrically noisy factory and building automation environments.
