Design a Custom BoardAbout This Component
Single-pole double-throw analog switch handling both analog and digital signals from 1.65V to 5.5V. Features 0.5ns typical switching speed, ~6Ω on-state resistance, and rail-to-rail signal handling with break-before-make operation. Ideal for signal routing, multiplexing, and bus switching in portable and IoT applications.
Package: SOT-23-6 · 6 pins
Why does this need a breakout?
SOT-23-6 packages house precision regulators, voltage references, and level shifters with 0.95mm pin pitch—too fine for hand soldering and incompatible with breadboards. A breakout board provides through-hole headers for prototype work, eliminating soldering difficulty while enabling quick circuit iteration. Essential for developing with compact analog and power management ICs.
