The ADM489AR is a low power, differential line transceiver designed for multipoint bus transmission lines, complying with EIA RS-485 and RS-422 standards. It supports full-duplex data transfer with a single differential line driver and receiver.
Key electrical specifications include a data rate of 250 kbps, a single 5V ± 10% supply, and a bus common-mode range of -7V to +12V. The device boasts a high input impedance of 12 kΩ, allowing up to 32 transceivers on the bus. It also features 2 kV EFT protection meeting IEC1000-4-4 and high EM immunity meeting IEC1000-4-3.
This transceiver is fabricated using BiCMOS technology, combining low power CMOS with fast switching bipolar technology. It is suitable for applications such as low power RS-485 and RS-422 systems, DTE-DCE interfaces, packet switching, local area networks, data concentration, data multiplexers, and ISDN.
The ADM489AR is available in SOIC packages and is designed for surface mount applications. It includes features like reduced slew rate for low EM interference, short-circuit protection, and excellent noise immunity, with a low supply current of 30 μA.
