ISL32740E FN8857
Rev.3.00
Oct 2, 2017 Isolated 40Mbps RS-485 PROFIBUS Transceiver The ISL32740E 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 2.5kVRMS isolation/600VRMS working voltage 3V to 5V power supplies The part is available in a 16 Ld QSOP package offering
unprecedented miniaturization, and in a 16 Ld SOICW
package providing a true 8mm creepage distance. 20ns propagation delay The ISL32740E is PROFIBUS compliant, including the
rigorous PROFIBUS differential output voltage
specifications. 50kV/Вµs (typical), 30kV/Вµs (minimum)
common-mode transient immunity A unique ceramic/polymer composite barrier provides
excellent isolation and 44,000 years of barrier life. Low EMC footprint The device is compatible with 3V as well as 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 Equipment covered under IEC 61010-1 Edition 3 1 2,8 -40В°C to +85В°C (EIBZ) -40В°C to +125В°C (EFBZ) Meets or exceeds ANSI RS-485 and
