The ISL32743E 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.
The part is available in a 16 Ld SOICW package
providing a true 8mm creepage distance.
A unique ceramic/polymer composite barrier provides
excellent isolation and 44000 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.

Notes:
1. Refer to TB347 for details about reel specifications.
2. 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. 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. For Moisture Sensitivity Level (MSL), refer to the ISL32743E product information page. For more information about MSL, refer to
TB363.
