ADM489AR Description

Short technical summary and product information.

The ADM489AR is a low power differential line transceiver designed for balanced data transmission on multipoint bus lines. It complies with EIA RS-485 and RS-422 standards and contains a single differential driver and receiver for full-duplex data transfer.

 

Key specifications include a data rate of 250 kbps, supply voltage range of 4.5V to 5.5V, and a bus common-mode range of -7V to +12V. The device features reduced slew rate for low electromagnetic interference, short-circuit protection with thermal shutdown, and 2 kV EFT protection per IEC1000-4-4. The input impedance of 12 kΩ allows up to 32 transceivers on the bus.

 

The transceiver is suitable for low power RS-485/RS-422 systems, DTE-DCE interfaces, packet switching, local area networks, data concentration, and multiplexers. It is available in a 14-SOIC surface mount package with a 14-SOIC supplier device package.
