CD4000 Series IC Set (10pcs Assorted DIP14/DIP16 Chips)
As someone working on hobby electronics and retro digital logic projects, I couldn’t resist this 10-piece assorted CD4000 series DIP IC set. It includes classics like CD4049, CD4017, CD4013, CD4051, and more—basically, all the essential building blocks for basic counters, flip-flops, and multiplexers. The price was about a third of what I’d pay for the same in the US through Mouser or Digi-Key.
What caught my attention: The variety and value. I’ve had trouble sourcing these chips locally without breaking the bank. AliExpress listed these as top-sellers with solid reviews, so I gave it a shot.
Performance & Experience: I tested a few of the ICs on a breadboard—CD4017 for a simple LED chaser and CD4040 for frequency division. All chips worked right out of the bag, no faulty pins, no fakes. They appear to be genuine or very close to original specs. Packaging was solid—wrapped in anti-static foam and bagged.
Pros:
-
Excellent value
-
Genuine performance
-
Great starter assortment for digital IC projects
Cons:
-
Delivery took 17 days to the US
-
No labeling sheet (I had to cross-reference part numbers manually)
Comparison: A similar 10-chip assortment costs at least $15–$20 from US sellers. I paid under $5 for this, including shipping.
Verdict: Exceeded expectations—fully functional, affordable, and exactly what I needed for DIY electronics.

CD4060, CD4066, CD4070, CD40106 IC Pack (10pcs DIP)
This 10-piece CD4060/CD4066/CD4070 logic IC set was another must-have for my workshop. I needed CD4060 for timing circuits, CD4066 for analog switches, and CD4070 for XOR logic gates. These are surprisingly hard to find affordably in one place in the States.
Why I bought it: I liked that this pack grouped some slightly less common CMOS chips together. I’ve seen these sell for $1.50–$2.00 per chip in local stores.
In use: I wired up a basic oscillator using CD4060 with a 100k resistor and 10uF cap—clean output. The CD4066 functioned well switching audio signals in a passive synth project. CD4070 worked flawlessly in a test XOR logic demo. No voltage or current irregularities.
Pros:
-
Rare ICs at a budget price
-
Arrived well-protected
-
Ideal for timed or audio switching circuits
Cons:
-
Slightly longer delivery (19 days)
-
No brand info, but still worked well
Price comparison: Under $6 for 10 chips is unbeatable. Just two of these chips would cost that in the US.
Expectation match: Absolutely. I was nervous about compatibility or fakes, but they held up under basic circuit testing.

CD4069 DIP14 Hex Inverter (10pcs)
The CD4069 DIP14 pack was a specific buy—I use inverters a lot for waveform shaping and oscillator building. These hex inverters are also great for Schmitt triggers and signal cleaning.
Reason for purchase: I’d burned out a couple of these in an overvoltage test and needed to replenish stock. Getting 10 of them at this price felt like a no-brainer.
Test drive: Hooked one up in a classic NOT gate arrangement. Output was sharp. I also used one chip in a square-wave oscillator setup—no issues with switching speed or logic level inconsistencies.
Pros:
-
All 10 ICs fully operational
-
Consistent voltage thresholds
-
Durable pins, easy breadboarding
Cons:
-
Generic packaging (no brand or manufacturing date)
Cost analysis: I paid about $0.40 per chip here. In the US, you’re looking at around $1–$1.50 per chip minimum.
Was it worth it? Absolutely. Got what I wanted, everything worked, and I now have enough inverters for months of experimentation.

CD4015, CD4019, CD4060, CD4070, CD4071 Combo Pack (10pcs)
This CD4015/CD4019 combo pack caught my eye because of the inclusion of shift registers and logic gates. I was specifically after the CD4015 for a data storage sequence and CD4071 for OR gate work.
Purchase motivation: Finding multiple function chips in one pack is rare. The versatility of this selection made it easy to justify.
My experience: I tested the CD4015 with a binary counter, and it latched bits beautifully. The CD4071 worked perfectly for combining logic outputs. CD4019 was unfamiliar to me, but it turned out to be a great tool for creating multi-input logic functions.
Pros:
-
Strong selection for logic experimentation
-
Useful for beginners and seasoned builders
-
Anti-static packaging preserved IC quality
Cons:
-
Slightly mixed date codes (some chips older stock)
US comparison: This set would easily run $20+ stateside, especially with lesser-known chips. I spent under $6.
Worth it? Without a doubt. I gained tools I’ll actually use in real builds.

SOP IC Chip Set (10pcs – CD4053BM, CD4060BM, etc.)
This SOP16 logic IC assortment was more of a speculative buy. I’m venturing into SMD soldering and needed inexpensive practice ICs—this mix includes CD4053BM, CD4066BM, CD4093BM, and more.
Why I bought it: I liked the challenge. Plus, these specific SMD chips are excellent for compact designs, and the price was incredibly low.
In practice: I mounted a few chips using hot air and tested their logic functions. CD4053BM and CD4060BM both performed exactly as expected. I used flux and pre-heated pads, and the chips soldered down beautifully.
Pros:
-
Works perfectly in SMD logic circuits
-
Great for prototyping or practicing SMD soldering
-
Impressive build quality despite low cost
Cons:
-
No pinout labels, had to download datasheets
-
Not ideal for breadboarding (obviously, since they’re SMD)
US price comparison: A single SOP CD4060BM chip sells for $2+ domestically. I got 10 mixed chips for about $4. Unreal deal.
Did it deliver? Big yes. These gave me confidence in AliExpress for SMD electronics.

CD4069UBM SOP14 Hex Inverter Pack (10–50pcs)
Lastly, I picked up this CD4069UBM SOP14 inverter pack mainly to build a buffer array for a microcontroller project. I went with the 20pcs option.
Reason for the purchase: I love hex inverters—they’re useful in clock shaping and signal routing. Having 20 identical SMD units lets me design small, tight PCBs without worrying about chip availability.
Real-world use: I soldered two onto a prototyping board. The logic thresholds were tight and responsive. Voltage drop was within spec. Very clean switching—no ghost signals or lag.
Pros:
-
Price-to-quantity ratio is unbeatable
-
Well-manufactured chips
-
Great for compact digital projects
Cons:
-
SOP14 footprint isn’t beginner-friendly
-
Requires a microscope or magnifier for manual soldering
US comparison: I’d pay ~$1.25 per chip here. For the 20 I bought, that’s a $25 value for under $5.
Did it live up to expectations? More than. Even with the cheap price, quality was solid.
US $0.55
Final Thoughts
I was honestly surprised how well these ICs from AliExpress performed. Every single chip I tested worked, and many of them were better than I expected for the price. Shipping was reasonable (most orders arrived within 2–3 weeks), packaging was protective, and I feel like I got excellent value across the board.
I’d absolutely recommend these to anyone building logic circuits, working on Arduino or Raspberry Pi peripherals, or even just starting out with electronics. Just double-check pinouts and plan your projects ahead.
And yes—I’ll be buying more.
