DATASHEET ISL32741E FN8944 Rev.2.00 PROFIBUS Compliant 6kV VDE-Reinforced Isolated RS-485 Transceiver Nov 30, 2017 The ISL32741E is a galvanically isolated, high-speed Features differential bus transceiver, designed for bidirectional 40Mbps data rate data communication on balanced transmission lines. The 6kV isolation/1000V working voltage RMS RMS device uses Giant Magnetoresistance (GMR) as its isolation technology. 12.8kV surge immunity The part is available in a 16 Ld SOICW package with 3V to 5V power supplies true 8mm creepage distance. 20ns propagation delay The ISL32741E is PROFIBUS compliant, including the 5ns pulse skew rigorous PROFIBUS differential output voltage specifications. 50kV/s (typical), 30kV/s (minimum) common-mode transient immunity A unique ceramic/polymer composite barrier provides 6kV reinforced isolation and 44,000 years of barrier life. 15kV ESD protection The device is compatible with 3V and 5V input supplies, Low EMC footprint allowing an interface to standard microcontrollers Thermal shutdown protection without additional level shifting. Temperature ranges available Current limiting and thermal shutdown features protect -40C to +85C (EIBZ) and against output short circuits and bus contention that may -40C to +125C (EFBZ) cause excessive power dissipation. Receiver inputs are a full fail-safe design, ensuring a logic high R-output if Meets or exceeds ANSI RS-485 and ISO A/B are floating or shorted. 8482:1987(E) Applications PROFIBUS compliant PROFIBUS-DP and RS-485 networks 0.3 true 8mm 16 Ld SOICW package Factory automation UL 1577 recognized Building environmental control systems VDE V 0884-10 certified Industrial/process control networks Related Literature Equipment covered under IEC 61010-1 Edition 3 For a full list of related documents, visit our website ISL32741E product page 3.3V 5V 5V 3.3V ISOLATION 100n 100n ISOLATION 100n 100n BARRIER BARRIER 1 16 16 1 390R 390R VDD1 VDD2 VDD2 VDD1 3 12 12 3 R A A R 4 4 RE 220R 220R RE 5 13 13 5 DE B B DE 6 10 10 6 D ISODE ISODE D 390R 390R GND1 GND2 GND2 GND1 1M 4.7n 4.7n 1M 2, 8 9,15 9,15 2, 8 ISL32741E ISL32741E Figure 1.

Add -T suffix for 1k unit or -T7A suffix for 250 unit tape and reel options. Refer to TB347 for details on reel specifications. 2. Intersil Pb-free plus anneal products employ special Pb-free material sets molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. 3.
