The ADM488A and ADM489A 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 RS-485 and RS-422 standards of the Electronics Industries Association (EIA). Both products contain a single differential line driver and a single differential line receiver, making them suitable for full-duplex data transfer. The ADM489A contains an additional receiver and driver enable control.\n\n The input impedance is 12 kΩ, allowing 32 transceivers to be connected on the bus. The ADM488A/ADM489A operate from a single 5 V ± 10% power supply.\n\n Excessive power dissipation that is caused by bus contention or output shorting is prevented by a thermal shutdown circuit. This feature forces the driver output into a high impedance state if, during fault conditions, a significant temperature increase is detected in the internal driver circuitry.The receiver contains a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating).\n\n The ADM488A/ADM489A are fabricated on BiCMOS, an advanced mixed technology process combining low power CMOS with fast switching bipolar technology.\n\n The ADM488A/ADM489A are fully specified over the industrial temperature range and are available in SOIC and MSOP packages.\n\nApplicationsLow power RS-485 and RS-422 systemsDTE-DCE interfacePacket switchingLocal area networksData concentrationData multiplexersIntegrated services digital network (ISDN)
