Design a Custom BoardAbout This Component
Quad analog switch IC containing four independent SPST (single-pole, single-throw) switches with typical on-resistance of 70 ohms. Each switch is independently controlled by a logic input, enabling analog signal routing and multiplexing. Operates across a wide voltage range and finds use in audio/video switching, instrumentation, and signal conditioning applications.
Package: TSSOP-14 (4.4×5mm) · 14 pins
Why does this need a breakout?
The 0.65mm pitch on this 14-pin package makes hand soldering tedious and error-prone without magnification and fine tools. A breakout board routes each pin to standard 0.1-inch headers, enabling breadboard prototyping and simplifying connections for LIN transceivers, ADCs, digital potentiometers, and microcontrollers that typically come in this footprint.
