ADM485JRZ

The ADM485JRZ is a differential line transceiver from Analog Devices, suitable for high-speed bidirectional data communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with EIA standards RS-485 and RS-422. The device operates from a single 5 V power supply and achieves a data rate of 5 Mbps.

Key features include thermal shutdown protection and short-circuit protection to prevent excessive power dissipation. The driver propagation delay is typically 10 ns, and the receiver propagation delay is typically 15 ns. The transceiver offers high-Z outputs when disabled or powered off, minimizing bus loading. It supports a bus common-mode range of -7 V to +12 V.

This transceiver is fabricated using BiCMOS technology, combining low power CMOS with fast switching bipolar technology. It is ideal for low power RS-485 systems, DTE/DCE interfaces, packet switching, local area networks, data concentration, data multiplexers, and integrated services digital networks (ISDN).

The ADM485JRZ is available in a SOIC-8 package, designed for surface mounting. Its dimensions are 5 mm in length, 4 mm in width, and 1.5 mm in height.
