Design a Custom BoardAbout This Component
Single-pole octal-throw analog multiplexer/demultiplexer IC with 8 independent channels selectable via 3-bit address inputs. Features low ON-state resistance (60-80Ω typical), wide analog voltage range (-5V to +5V), address latch capability, and integrated ESD protection. Suitable for analog/digital signal routing, multiplexing, and demultiplexing applications in mixed-signal circuits.
Package: SOIC-20W (7.5mm wide) · 20 pins
Why does this need a breakout?
The 1.27mm pin pitch makes hand-soldering this 20-pin SOIC challenging and error-prone. A breakout board brings all pins to standard 0.1" spacing, enabling reliable breadboard prototyping and simplifying development of USB-to-UART interfaces without requiring reflow soldering or specialized equipment.
