ST485BDR ST Drivers and Receivers

The ST485BDR is a low-power transceiver for RS-485 and RS-422 communication from STMicroelectronics in SOIC-8 package, containing one driver and one receiver for half-duplex bidirectional data communication on multipoint bus transmission lines . For selection, verify single 5V supply (4.75V to 5.25V), confirm data rate up to 2.5Mbps, note low quiescent current of 300µA typical, common-mode input voltage range of -7V to +12V, 70mV typical input hysteresis, 30ns propagation delay with 5ns skew, and operating temperature from -40°C to +85°C . Features include driver current limiting, thermal shutdown protection, and support for up to 64 transceivers on the same bus with driver maintaining high impedance in 3-state or power-off conditions . Ideal for industrial control systems, building automation, networked security systems, data loggers, and energy management equipment requiring reliable long-distance RS-485 communication.
