Design a Custom BoardAbout This Component
Single-pole single-throw analog switch IC with two I/O terminals and digital enable control. Features low ON resistance (45Ω typical at 4.5V, 25Ω at 9V), wide 2-10V supply range, and TTL-compatible input thresholds. Ideal for signal routing, multiplexing, and precision analog switching applications.
Package: SC-74A-5 · 5 pins
Why does this need a breakout?
Tiny 0.95mm pitch SMD makes hand-soldering risky and breadboarding impossible. A breakout board brings these single-gate logic ICs and analog switches to standard 0.1" headers, enabling rapid prototyping and reliable connections without microscopy skills or rework tools.
