ADM2484E 5 kV Signal Isolated, ESD Protected, 500 kbps, Full/Half Duplex RS-485 Transceiver
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 half-duplex 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 Analog Devices, Inc., 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.
