Design a Custom BoardAbout This Component
Half-duplex RS-485/RS-422 transceiver with one driver and one receiver, supporting data rates up to 2.5Mbps. Operates from single 5V supply with 120-500µA current consumption and includes driver short-circuit protection, thermal shutdown, and fail-safe receiver logic. Suitable for industrial control networks, low-power serial communication, and EMI-sensitive applications.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
