GENERAL DESCRIPTION

The ADM488 and ADM489 are low power, differential line transceivers suitable for communication on multipoint bus transmission lines. They are intended for balanced data transmission and comply with both Electronics Industries Association (EIA) RS-485 and RS-422 standards. Both products contain a single differential line driver and a single differential line receiver, making them suitable for full-duplex data transfer. The ADM489 contains an additional receiver and driver enable control.
