Design a Custom BoardAbout This Component
Half-duplex RS-485 transceiver IC in 8-pin SOIC package. Provides differential signaling for multi-drop industrial communication networks with integrated driver and receiver functionality. Commonly used in HVAC controls, building automation, and industrial equipment requiring robust noise immunity and long-distance serial 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.
