to a higher voltage 5V supply for communication of strong bus signals across 100 meters and longer distances. The ISL3274xE transceivers are fully compliant with the EN 50081 and EN 50082-2 electromagnetic compatibility (EMC) standards and the umbrella line-voltage standard for information technology equipment (ITE) EN 61000. “Our latest high-speed RS-485 isolated transceivers radiate virtually no EMI, and they eliminate ground loops between bus nodes to protect data transmission,” said Philip Chesley, vice president of Industrial Analog and Power products at Intersil. “The ISL32741E’s high working voltage and ability to push its reinforced isolation barrier up to 6kV enables customers to solve their most difficult IIoT networking design problems. Key Features and Specifications of ISL32741E and ISL32740E Family 40Mbps data rate enables high-speed data transmission Supports 3V to 5V power supplies Offers 5ns pulse skew and 20ns propagation delay TheISL32741Eoffers6kVRMSisolation/1,000VRMS working voltage, and 12.8kV surge immunity TheISL32740Eoffers2.5kVRMSisolation/600VRMS working voltage Single unit load allows up to 160 devices on the bus 50kV/µs (typ), 30kV/µs (min) common-mode transient immunity provides reliable data transmission in noisy environments Offers a barrier lifetime of 44,000 years 15kV ESD bus-pin protection, and low EMC footprint Thermal shutdown protection prevents damage during bus contention, or excessive current PROFIBUS compliant The ISL3274xE can be combined with the ISL28025 precision digital power monitor, ISL12022M low power real time clock, and Renesas MCUs to create a system solution.

Defined spacing between PCBs! WR-BTB is a new family of signal plug connectors from Würth Elektronik eiSos suitable for SMT assembly. The plugs with coded guide are available in versions with 40, 64, 80 or 100 pins. The models with 0.8 and 1-mm pitch are also available in various heights. Various male and female plugs can be combined to achieve precisely defined spacing between two boards through the use of stable board-to-board connectors – so purely mechanical spacers may not be necessary and could be dispensed with, under certain circumstances. WR-BTB connectors with 1-mm pitch are achievable with a board spacing of 7.6 mm, 9.6 mm, 11.6 mm, 12.6 mm and 14.6 mm. The 0.8-mm pitch plugs allow even more combination options for spacing from 4.9 mm to 15.9 mm. The high-grade connectors are specified for operating temperatures from -55 to +85°C. The plugs are available from Würth Elektronik eiSos from stock in unlimited quantities and free samples can be requested.
