10pcs SN74AHCT125N SN74 Quadruple Bus Buffer Gates with 3-State Outputs IC DIP-14.

Picked these up while troubleshooting a WS2812 LED strip that was flickering when driven from an ESP32. The 3.3V data signal wasn’t quite enough for the strip, so I needed a proper 3.3V → 5V logic level conversion. Used one of these SN74AHCT125 chips and the flicker disappeared immediately. Signal is clean now and the strip runs perfectly. If you're running addressable LEDs from an ESP32 or other 3.3V microcontroller, these work great as a simple level shifter. Exactly what I needed.

I've only used one so far, but works well with my WLED project.

I used these to multiplex a single 8Mhz SPI channel to four sets of dotStar LED strips. Worked flawlessly. Served to both multiplex and level shift. 3.3v ESP32 gpio's drove the inputs, 5.0v outputs fed to the dotStar LED strips.

Picked these up for WLED projects using WS2812b LEDs and they work exactly like they should. They work so much better than the i2c level shifters that I've used in the past (which, by the way, if I had read all of the WLED Basics page, I would have gotten these first). If you are doing anything with WS281x lights, pick these up, you will need them.

Good quality ICs! I received TI (Texas Instruments) branded parts. They are known for quality ICs. They seem to function perfectly. The bundle size is a good value for the price. Recommended!!

Great level shifter to use with weld controllers

As described

They do what there supposed to do, seem of good quality.
