Analog Devices ADM488 Manuals

ADM488/ADM489 is a full-duplex, low power, slew rate limited EIA RS-485 transceiver. It meets EIA RS-485 and RS-422 standards with a data rate of 250 kbps. The transceiver operates on a single 5V ± 10% supply voltage and has a -7V to +12V bus common-mode range. It features a 12 kΩ input impedance, 2 kV EFT protection, high electromagnetic immunity, reduced slew rate for low EM interference, short-circuit protection, and excellent noise immunity. The transceiver is suitable for low power RS-485 and RS-422 systems, DTE-DCE interfaces, packet switching, local area networks, data concentration, and integrated services digital network (ISDN) applications.
