Design a Custom BoardAbout This Component
Half-duplex RS-485 transceiver in 8-SOIC package for industrial serial communications. Converts between TTL/CMOS logic levels and differential RS-485 signaling with integrated slew-rate limiting. Supports multi-drop networks up to 32 nodes with robust EMI immunity and short-circuit protection.
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.
