The ADM2483 differential bus transceiver is an integrated, galvanically isolated component designed for bi-directional data communication on multi-point bus transmission lines. It is designed for balanced transmission lines and complies with ANSI TIA/EIA RS-485-A and ISO 8482:1987(E). The ADM2483 employs Analog Devices’ iCoupler technology to combine a 3-channel isolator, a 3-state differential line driver and a differential input receiver into a single package. The logic side of the device can be powered with either a 5 V or a 3 V supply while the bus-side is powered with a 5 V supply.

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.

For detailed drawings and chemical composition please consult our  Package Site

Pin Count is the number of pins, balls, or pads on the device. Pin-out diagrams & pin function descriptions may be found in the datasheet.

This is the acceptable operating range of the device. The various ranges specified are as follows:

• Commercial: 0 to +70 degrees Celsius
• Military : -55 to +125 degrees Celsius
• Industrial: Temperature ranges may vary by model. Please consult the datasheet for more information.
• Automotive: -40 to +125 degrees Celsius
