GENERAL DESCRIPTION

technology to combine a 3-channel isolator, a three-state

differential line driver, and a differential input receiver into a

single pacꢀage.

The ADM2484E is an isolated data transceiver with ±±1 ꢀk

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

linꢀs externally to Receiver Input Pin A, and Transmitter

Output Pin Z linꢀs externally to Receiver Input Pin B.

The differential transmitter outputs and receiver inputs feature

electrostatic discharge circuitry that provides protection up to

±±1 ꢀk using the human body model (HBM). The logic side of

the device can be powered with either a 1 k or a 3.3 k supply,

whereas the bus side requires an isolated 3.3 k supply.

Designed for balanced transmission lines, the ADM2484E

complies with ANSI TIA/EIA RS-481-A-±998 and ISO 8482:

±987(E). The device employs Analog Devices, Inc., iCoupler®

The device has current-limiting and thermal shutdown features

to protect against output short circuits and situations where bus

contention causes excessive power dissipation.
