ISL32741E FN8944
Rev.1.00
Aug 24, 2017 PROFIBUS Compliant 6kV VDE-Reinforced Isolated RS-485 Transceiver The ISL32741E is a galvanically isolated, high-speed
differential bus transceiver, designed for bidirectional
data communication on balanced transmission lines. The
device uses Giant Magnetoresistance (GMR) as its
isolation technology. Features 40Mbps data rate 6kVRMS isolation/1000VRMS working voltage 12.8kV surge immunity The part is available in a 16 Ld SOICW package with
true 8mm creepage distance. 3V to 5V power supplies The ISL32741E is PROFIBUS compliant, including the
rigorous PROFIBUS differential output voltage
specifications. 5ns pulse skew A unique ceramic/polymer composite barrier provides
6kV reinforced isolation and 44,000 years of barrier life.
The device is compatible with 3V and 5V input supplies,
allowing an interface to standard microcontrollers
without additional level shifting.
Current limiting and thermal shutdown features protect
against output short circuits and bus contention that may
cause excessive power dissipation. Receiver inputs are a
full fail-safe design, ensuring a logic high R-output if
A/B are floating or shorted. Applications 20ns propagation delay 50kV/Вµs (typical), 30kV/Вµs (minimum)
common-mode transient immunity 15kV ESD protection Low EMC footprint Thermal shutdown protection Temperature Ranges available -40В°C to +85В°C (EIBZ) and -40В°C to +125В°C
