Description
The IL3185 and IL3122 are galvanically isolated, differential
bus transceivers designed for bidirectional data
communication over balanced transmission lines. The
devices use NVE’s patented* IsoLoop spintronic Giant
Magnetoresistance (GMR) technology. The IL3185 delivers
at least 1.5 V into a 54 load, and the IL3122 at least 2 V
into a 100 load for excellent data integrity over long
cables. These devices are also compatible with 3 V input
supplies, allowing interface to standard microcontrollers
without additional level shifting.
Both the IL3185 and IL3122 have current limiting and
thermal shutdown features to protect against output short
circuits and bus contentions that may cause excessive power
dissipation. The receivers also incorporate a “fail-safe if
open” design, ensuring a logic high on R if the bus lines are
disconnected or “floating.”
