Description
The IL3285 and IL3222 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 IL3285 delivers
at least 1.5 V into a 54 load, and the IL3222 at least 2 V
into a 100 load for excellent data integrity over long
cables. These devices are also compatible with 3.3 V input
supplies, allowing interface to standard microcontrollers
without additional level shifting.
A unique ceramic/polymer composite barrier provides
excellent isolation and virtually unlimited barrier life.
Both the IL3285 and IL3222 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.”
Receiver input resistance of 96 k is eight times the RS-485
“Unit Load” (UL) minimum of 12 k. Thus these products
are known as “one-eighth UL” transceivers. There can be up
to 256 on a network while still complying with the RS-485
loading specification.
