Description
The IL3522 is a galvanically isolated, high-speed differential bus
transceiver, designed for bidirectional data communication on
balanced transmission lines. The device uses NVE’s patented*
IsoLoop spintronic Giant Magnetoresistance (GMR) technology.
A unique ceramic/polymer composite barrier provides excellent
isolation and virtually unlimited barrier life.
The IL3522 delivers an exceptional 2.3 V differential output into a
54 load over the supply range of 4.5 V to 5.5 V. This provides
better data integrity over longer cable lengths, even at data rates as
high as 40 Mbps. The device is also compatible with 3 V supplies,
allowing 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 feature a “fail-safe if open”
design, ensuring a logic high R-output if A/B are floating.
