- TIDA-00540 – RS-485 / RS-232 Multiprotocol Transceiver Reference Design
Our RS-232 devices help you increase security and safety in your factory and automation control applications.
For your industrial PC, programmable logic controller or other factory automation and control designs, our RS-232 devices have International Electrotechnical Commission electrostatic discharge protection as high as 15 kV on all pins, to protect against electrostatic discharges encountered during handling and assembly. Operating temperatures from –40°C to 85°C and 0°C to 70°C – with even wider ranges in our automotive-qualified (-Q1) (–40°C to 125°C) and Enhanced Product (-EP) (–55°C to 125°C) devices – enable protected, secure communication.

Achieve fast data speeds while reducing power consumption in your wired networking designs
For your edge router, small business switches or other wired networking designs, communicate with other peripherals at the data rates you need, with devices that have speeds ranging from 7 kbps to 1 Mbps. Even at these fast speeds, it is still possible to reduce power consumption through our power-down features (power down, auto power down and auto power down plus) and wide availability of supply voltages (2.5 V to 12 V).
