Design a Custom BoardAbout This Component
Single-pole single-throw analog switch with low ON-resistance (45Ω typical at 4.5V) and digital enable control. Features wide supply range of 2.0V to 10.0V, CMOS low power dissipation, and integrated ESD protection exceeding 2000V HBM. Suitable for signal routing, multiplexing, and analog switching applications requiring minimal signal distortion.
Package: SOT-353 · 5 pins
Why does this need a breakout?
SOT-353 packages feature 0.65mm pin pitch and tiny 1.9×2.7mm dimensions, making hand soldering and breadboarding impractical. A breakout board converts these compact leads to standard headers or through-holes, enabling reliable prototyping of analog sensors, op-amps, and voltage regulators without specialized equipment or microscopy.
