GENERAL DESCRIPTION
The ADM485E/ADM487E/ADM1487E are 5 V, low power data transceivers with ±15 k V ESD protection suitable for halfduplex munication on multipoint bus transmission lines. They are designed for balanced data transmission and ply with Telemunication Industry Association/Electronics Industries Association (TIA/EIA) standards RS-485 and RS-422. The ADM487E and ADM1487E have a 1/4 unit load receiver input impedance that allows up to 128 transceivers on a bus, whereas the ADM485E allows up to 32 transceivers on a...
