ADM1487EARZ-REEL7

The ADM1487EARZ-REEL7 RS-485 transceiver is a versatile and robust communication solution that complies with TIA/EIA RS-485/RS-422 standards. It offers exceptional ESD protection (±15 kV HBM) on RS-485 I/O pins, making it highly reliable. With flexible data rates, including 250 kbps and 2.5 Mbps, it caters to various communication needs. Operating in half-duplex mode and featuring reduced slew rates for lower EMI, this transceiver is well-suited for industrial and automotive applications. Its wide common-mode input range, thermal shutdown, short-circuit protection, and compact 8-lead SOIC package make it an ideal choice for challenging environments. Additionally, the ADM487EW variant is qualified for automotive applications, ensuring it meets stringent automotive industry standards. Overall, the ADM1487EARZ-REEL7 is a comprehensive and adaptable communication solution for a wide range of applications.

The ADM485E/ADM487E/ADM1487E are 5 V, low power data transceivers with ±15 kV ESD protection suitable for half-duplex communication on multipoint bus transmission lines. They are designed for balanced data transmission and comply with Telecommunication Industry Association/Electronics Industries Association (TIA/EIA) standards RS-485 and RS-422. The ADM487E and ADM1487E have a 1/4 unit load receiver input impedance that allows up to 128 transceivers on a bus, whereas the ADM485E allows up to 32 transceivers on a bus. Because only one driver is enabled at any time, the output of a disabled or power-down driver is three-stated to avoid overloading the bus.

The driver outputs are slew rate limited to reduce EMI and data errors caused by reflections from improperly terminated buses. Excessive power dissipation caused by bus contention or output shorting is prevented with a thermal shutdown circuit. The parts are fully specified over the industrial temperature ranges and are available in 8-lead SOIC packages.
