ADM485EARZ-REEL7
Description
Technical Parameters
The ADM485EARZ-REEL7 RS-485 transceiver is a high-performance solution compliant with TIA/EIA RS-485/RS-422 standards. Noteworthy features include robust ESD protection, support for data rates up to 2.5 Mbps in half-duplex mode, reduced slew rates for low EMI, and a broad common-mode input range of -7 V to +12 V. With thermal shutdown and short-circuit protection mechanisms, this transceiver ensures reliability and safety in challenging conditions. Available in an 8-lead SOIC package and with an automotive-qualified variant (ADM487EW), it proves to be a versatile and resilient choice for industrial and automotive communication applications.

GENERAL DESCRIPTION：
The ADM485E/ADM487E/ADM1487E are 5 V, low power data transceivers with ±15 kV ESD protection suitable for halfduplex 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.
