Design a Custom BoardAbout This Component
Low-power RS-485/RS-422 half-duplex transceiver containing one driver and one receiver. Operates from single 5V supply with 300µA typical quiescent current, 30ns propagation delay, and supports up to 64 devices on bus. Features thermal shutdown, current limiting, and 7-12V common-mode input range for robust multipoint communication.
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.
