Worked well to extend the number of pins on a Raspberry Pi Pico

I am using it to chain 32 lights together. It was easy to understand and use. Have used 3 of them so fair , all of them work well.

The product I received is definitely not from TI.

Das günstigste Angebot für dieses adressierbare Latch, als Portextender am Arduino ganz nützlich.Alle Chips funktionieren wie erwartet (Testschaltung am ATMega gebastelt), aber ob sich Texas Instruments sooo schlechte Prints erlaubt...???

I've purchased a number of products from Bojack, so I was surprised that these chips failed to perform as expected. Not one of the batch held up. I used a heat sink to counter overheating and had failures with the simplest of test applications: hooked up to the Arduino, light up LEDs in sequence from 00000001 to 10000000. The process worked for a minute or so, then died dismally. I substituted another chip from the batch and .... same problem. I checked for shorts in the breadboard wiring and found none.Consequently, I tossed all the chips.As I stated above, other Bojack products have performed as expected. Not these guys.

all that I tested have the same flaw... do not cascade properly @5v .. QH' pulses when shifting a '1' from QG to QH. this causes the downstream chip to set its QA high... noted that all that I tested work as expected @3.3v.update: maybe I'm damaging these by running @5v? 70ma current limit?? should learn more about these and post a more informed review.if i am damaging them, it is a subtle failure since they still work @3.3v....maybe it would be better if when you damage them, they self destruct? with the magic smoke?

its a pretty cut and dry purchase. they give you a good amount of SIPO shift registers for a decent price, and they work

Arrived quickly and undamaged within the protective plastic box (photo 1). I've only tested four of the 25 as pictured in photo 2 (buried under the 32 resistors). These 595's really solve the pin-shortage issue for many application designs. Photo 3 shows a nano MCU controlling the 128 individual LEDs (matrix) via four 595s and only three control pins (i.e. data, clock, latch/trigger). This technique is so common the Arduino IDE provides the shiftOut() function to take care of the details. I also purchased this set of ICs so my ATtiny85's would have an opportunity to control more complex outputs since it only has five digital pins max. (and less if using analog or PWM or I2C circuits); these shift registers give the Tiny85 a chance to do even more. So far, these ICs operate flawlessly. I recommend and would buy again.
