SN74AHCT125-Based Level Shifter - 3.3V to 5V (Ideal for WS2811)

Please Note! These are NOT modules for use with the Tetra or Octo2Go controllers!
They are intended for those who wish to build their own controllers on a breadboard using an ESP32 or 8266. These devices are already built-in to every controller we sell - so no need to upgrade!


The SN74AHCT125-Based Level Shifter is a high-performance, reliable unidirectional solution designed to seamlessly interface 3.3V logic devices with 5V systems, making it perfect for use with WS2811 LED controllers or similar applications. This level shifter utilizes the SN74AHCT125 chip, a quad buffer renowned for its fast switching speeds and low power consumption.

Key Features:

  • Ideal for WS2811: Provides the correct voltage level for driving WS2811 LEDs, ensuring reliable data transmission and pixel control.
  • Fast Switching Speed: Ensures smooth, glitch-free signal transmission, even for high-speed data rates required by modern LED control protocols.
  • Low Power Consumption: Optimized for efficiency, it operates with minimal power draw, making it suitable for battery-powered projects and low-power devices.
  • Stable and Reliable: With a wide voltage range, the SN74AHCT125 ensures consistent performance and high noise immunity across a variety of environments.

Applications:

  • WS2811/WS2812 LED Strips: Perfect for interfacing between 3.3V microcontrollers and 5V-based WS2811/WS2812 LEDs.
  • Microcontroller Interfacing: Use it to connect 3.3V logic output devices (like Raspberry Pi, Arduino, or ESP8266/ESP32) to 5V input peripherals.
  • Signal Conversion: Great for projects involving different voltage logic levels where accurate signal translation is required.

Why Choose This Level Shifter?

Don't make the same mistakes we did! The i2C level shifters you find on Amazon are NOT fast enough to handle LEDs! Get the best results here, built using genuine Texas Instruments chips!

How to use:

  • Make sure you connect both GND and 5V to the marked pins.
  • Connect your signal source (ESP8266/ESP32) to the "A" side (e.g. 1A)
  • Connect your pixel's data-in pin (DI) to the "Y" side (e.g. 1Y)
  • Each chip supports 4 separate inputs/outputs

Specifications:

  • Logic Supply Voltage: 3.3V / 5V
  • Output Voltage Range: 0V to 5V
  • Maximum Speed: Up to 25 MHz
  • Operating Temperature Range: -40°C to 125°C
