High-Speed RS-485 Transceivers Target IIoT Networks

Intersil, a subsidiary of Renesas Electronics, has announced two new high-speed, isolated RS-485 differential bus transceivers that provide 40 Mbps bidirectional data communication for Industrial Internet of Things (IIoT) networks. The ISL32741E offers 1,000 VRMS working voltage and 6 kV of reinforced isolation, more than 2x higher than Intersil isl32740e-41e-transceiver-promocompetitive solutions. The higher working voltage and reinforced isolation is required for today’s most rigorous medical and high-speed motor control applications. The ISL32740E with 2.5kV of isolation and 600VRMS working voltage comes in a small package, enabling high channel density for programmable logic controllers (PLCs) in factory automation applications.

The ISL3274xE transceivers provide additional advantages over other isolation technologies, including ultra-low radiated emission and EMI susceptibility, support for up to 160 devices on the bus, and an extended 125°C temperature range. These devices leverage giant magneto-resistance (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. The ISL32740E and ISL32741E 40 Mbps RS-485 transceivers are available now with prices ranging from $3.79 to $4.79 depending on package type and temperature range. Evaluation boards are available for $99.
