Picture this: you're wiring up a logic circuit on your breadboard, everything's clicking, then bam—no more CD4011 NAND gates. Frustrating, right? This 40-piece CDXX series kit has your back with two of each essential CMOS IC you use all the time, so you can prototype without interruptions.
We've curated 20 types that cover gates, flip-flops, multiplexers, counters, and oscillators—core building blocks for digital electronics:
Each chip is brand-new, individually packaged, and ready to drop into your next circuit.
CMOS means they sip power—great for battery-powered gadgets or long-running setups. They play nice with 3-15V supplies, matching Arduino, Raspberry Pi, or classic 5V logic. Static protection keeps them reliable through soldering sessions.
Breadboard a frequency divider with the CD4060 for a custom clock. Chain CD4017s for LED sequencers that dance to music. Mux inputs with CD4051 for sensor arrays. Repair vintage synths or build a BCD display with CD4511. Students, hobbyists, and pros alike grab this kit to skip part-hunting hassles.
At 40 pieces total, it's compact enough for your drawer but stocked for dozens of experiments. Whether you're learning Boolean algebra hands-on or tweaking IoT prototypes, these ICs deliver consistent performance every time. Grab yours and keep the sparks flying—literally or figuratively.
