ADM485AQ

The ADM485AQ is a differential line transceiver designed for balanced data transmission on multipoint bus lines. It complies with EIA RS-485 and RS-422 standards, operating from a single 5V supply. The device integrates one differential driver and one differential receiver, each independently enabled, with three-state outputs when disabled. Key specifications include a maximum data rate of 5 Mbps, typical driver propagation delay of 10 ns, and typical receiver propagation delay of 15 ns. The bus common-mode input range is -7V to +12V, ensuring robust operation in noisy environments. The transceiver incorporates thermal shutdown protection and short-circuit current limiting for fault tolerance. The ADM485AQ is available in an 8-pin ceramic DIP (CDIP) package with a 0.300" body width, designed for through-hole mounting. This package is suitable for industrial and military temperature range applications, though the exact operating temperature range is not specified in available data. The device is ideal for low-power RS-485 systems, DTE/DCE interfaces, local area networks, data multiplexing, and ISDN applications.
