The low-power, high-speed transceivers of this family are designed for RS-485, RS-422 and RS-423 communication applications. They usually contain one driver and one receiver in half duplex configuration. Each driver output and receiver input is protected against electrostatic discharge up to ± 15 kV and has no latch-up. These transceivers operate with a 5 V supply and draw a very low supply current when unloaded or fully loaded but with disabled drivers.
A SERCOS interface controller for industrial control systems enables real-time communication via optical fiber rings, RS-485 rings and RS-485 buses.

Low-power RS-485 transceiver with selectable data rate and compatible with 1.8 V I/Os
A 3.3 V differential line transceiver for RS-485 data transmissions in half-duplex mode, the STR485LV includes an external slew rate select pin able to switch between a fast data rate up to 20 Mbps or a slow data rate up to 250 kbps for longer cables.
Able to interface directly with voltage logic from 1.8 to 3.3 V, this differential driver/receiver is robust over fast transient burst IEC61000-4-4 Class B conditions and the bus pins withstand over ±8kV contact discharge and ±16kV air discharge conditions without latch-up, exceeding IEC 61000-4-2 specifications.
Available in a small (3 x3 mm) DFN10 package with a temperature range from –40 up to +105 °C, the STR485LV is a perfect fit for a wide range of applications including telecom infrastructure, high-speed data links, and low-voltage microcontroller communications.
