Description
The IL3585 is a galvanically isolated, high-speed differential bus
transceiver, designed for bi-directional data communication on
balanced transmission lines. Isolation is achieved through patented*
Isoloop® technology. The IL3585 offers an exceptional 2.5 V
differential output into a 54 Ωload, which translates to better data
integrity over longer cable lengths, even at data rates as high as 40
Mbps. The device is also compatible with 3.3V input supplies,
allowing interface to standard microcontrollers without the need for
additional level shifting components.
The IL3585 has current limiting and thermal shutdown features to
protect against output short circuits and bus contention situations
which may cause excessive power dissipation.
Isoloop® is a registered trademark of NVE Corporation.
*U.S. Patent number 5,831,426; 6,300,617 and others.
