ADM489AN Description

Short technical summary and product information.

The ADM489AN is a low power, differential line transceiver designed for balanced data transmission on multipoint bus lines. It complies with both EIA RS-485 and RS-422 standards and contains a single differential line driver and a single differential line receiver, making it suitable for full-duplex data transfer.

 

Key electrical specifications include a supply voltage range of 4.5V to 5.5V, a data rate of 250 kbps, and a quiescent supply current of only 30 µA. The device features a 12 kΩ input impedance, allowing up to 32 transceivers to be connected on the same bus. It also offers a common-mode voltage range of -7V to +12V and 2 kV EFT protection per IEC1000-4-4.

 

The ADM489AN is housed in a 14-lead PDIP package (14-DIP, 0.300" body width) and is designed for through-hole mounting. It is suitable for low power RS-485 and RS-422 systems, DTE-DCE interfaces, packet switching, local area networks, data concentration, and multiplexers.
