Design a Custom BoardAbout This Component
Single-pole single-throw analog switch IC with low on-resistance (45Ω typical at 4.5V) suitable for signal routing and multiplexing applications. Features wide 2.0V to 10.0V supply range, digital enable control, and integrated ESD protection exceeding 2000V HBM. Operates across -40°C to +125°C in a compact 5-lead TSSOP package.
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.
