RS485 transceiver
14 November 2018, Telecoms, Datacoms, Wireless, IoT

The STMicroelectronics STR485LV 3,3 V transceiver for RS485 applications enhances design flexibility by providing an external pin to select 20 Mbps or 250 Kbps communication and interfacing directly with low-voltage logic down to 1,8 V.

The user-selectable data rate allows designers to specify the same device and thus simplify inventory management for RS485-networking applications, ranging from high-speed/short-range up to the maximum communication distance (1220 m) depending on cable performance. It is ideal for a wide variety of scenarios, including telecom infrastructure, high-speed data links, or low-voltage microcontroller communications.

Designers get the flexibility to connect low-voltage logic devices from 1,8 V to 3,3 V directly, without needing level-shifting components, leveraging the 1,65 3,6 V supply-voltage range for data and enable signals. By maintaining internal driver-output resistance above 96 Ω up to 105°C, the STR485 allows up to 256 transceivers on the same bus in accordance with the RS485 specification.

Rich features for safety and robustness include thermal shutdown to prevent bus contention or faults causing excessive power consumption, and a receiver failsafe mode that prevents errors if inputs are idle, shorted, or unconnected. The bus pins withstand over ±8 kV contact discharge and ±16 kV air discharge without latch-up, exceeding IEC 61000-4-2 specifications, and are resistant to IEC61000-4-4 fast transient burst class-B.
