Achieve fast data speeds while reducing power consumption in your wired networking designs

Explore our RS-232 device portfolio for your data center and enterprise designs.

Our products for your rack server, server motherboard, and other data center and enterprise applications include RS-232 transceivers suitable for connecting with microcontrollers (MCUs) and microprocessors, with multiple transmitter and receiver configurations (one and one, two and two, and three and five). Devices with integrated level shifters enable interfacing with low-voltage MCUs, while a variety of package options include very thin quad flat no-lead.

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).
