ST485ECDR ST Drivers and Receivers

The ST485ECDR is a low-power RS-485/RS-422 transceiver from STMicroelectronics in SO-8 package, operating from single 5V supply with half-duplex configuration containing one driver and one receiver . For selection, verify supply voltage from 4.75V to 5.25V, confirm data rate up to 5Mbps, note 30ns propagation delay with 5ns skew, common-mode input voltage range from -7V to +12V, 70mV typical input hysteresis for noise immunity, and operating temperature from 0°C to +70°C . Features include ±15kV HBM ESD protection (IEC 1000-4-2 contact discharge ±8kV), current limiting and thermal shutdown for driver overload protection, driver maintains high impedance in 3-state or power-off conditions, low quiescent current of 300µA, and support for up to 256 transceivers on the same bus . Ideal for industrial fieldbus networks, building automation, security systems, data loggers, POS terminals, and energy management equipment requiring reliable long-distance RS-485 communication with high ESD robustness.
