Product Introduction
The ADM2484E is an isolated data transceiver with ±15 kV ESD protection suitable for high speed, half- or full- duplex communication on multipoint transmission lines. For halfduplex operation, the transmitter outputs and receiver inputs share the same transmission line. Transmitter Output Pin Y links externally to Receiver Input Pin A, and Transmitter Output Pin Z links externally to Receiver Input Pin B.
Designed for balanced transmission lines, the ADM2484E complies with ANSI TIA/EIA RS- 485- A- 1998 and ISO 8482: 1987(E). The device employs iCoupler technology to combine a 3- channel isolator, a three- state differential line driver, and a differential input receiver into a single package.
The differential transmitter outputs and receiver inputs feature electrostatic discharge circuitry that provides protection up to ±15 kV using the human body model (HBM). The logic side of the device can be powered with either a 5 V or a 3.3 V supply, whereas the bus side requires an isolated 3.3 V supply.
The device has current- limiting and thermal shutdown features to protect against output short circuits and situations where bus contention causes excessive power dissipation.
