IL3585E

The IL3585E is a PROFIBUS compatible isolated RS485 Interface with 100% matte tin lead frame plating. It 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 2.3V differential output into a 54Ω load, over the supply range of 4.5V to 5.5V. This means better data integrity over longer cable lengths, even at data rates as high as 40Mbps. The device is also compatible with 3.3V input supplies, allowing interface to standard microcontrollers without the need for additional level shifting components. It has current limiting and thermal shutdown features to protect against output short circuits and bus contention situations that may cause excessive power dissipation.
