ST3485ECDR ST Drivers and Receivers

The ST3485ECDR is a low-power RS-485/RS-422 transceiver from STMicroelectronics in SOIC-8 package, operating from a single 3.3V supply with ±15kV IEC 61000-4-2 ESD protection on bus pins and supporting data rates up to 12Mbps . For selection, verify supply voltage from 3V to 3.6V (3.3V nominal), common-mode input voltage range from -7V to +12V, low shutdown supply current of 1µA maximum, up to 64 transceivers on the same bus, and operating temperature from 0°C to +70°C . Features include current limiting and thermal shutdown for driver overload protection, guaranteed high receiver output state for floating inputs (fail-safe), industry-standard 75176 pinout, and interoperability with 5V logic levels . The half-duplex configuration contains one driver and one receiver. Ideal for industrial fieldbus networks, building automation, security systems, data acquisition, HVAC control, and any RS-485 communication requiring low power consumption, high data rate, and robust ESD protection in space-constrained designs .
