Designed for stable data transmission and superior latch-up immunity exceeding 250mA, it operates reliably across a wide temperature range (-40°C to 85°C). Packaged with anti-static protection and pin safety, this 10-piece set is ideal for professionals seeking dependable logic level shifting and bus buffering in complex electronic systems. ## Description The SN74AHCT125N is a quadruple Bus Buffer Gate featuring independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE)\ input is high. When OE\ is low, the respective gate passes the data from the A input to its Y output. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver Logic device type: Buffered, non-inverted Minimum power supply voltage: 4.5V Maximum power supply voltage: 5.5V Minimum working temperature: -40°C Maximum working temperature: 85°C Package include: 10pcs*SN74AHCT125N Review: Fixed my WS2812 LED flicker - 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. Review: Works great - This is my first time using Logic Level Converters and once I understood the pinout (would have been nice to have a sheet included, but it's easily searchable) I was happy how easy it was. I'm sure i'll buy again. ## Features - Inputs are TTL-voltage compatible - Latch-up performance exceeds 250mA per JESD 17 - High-current 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers. - The product has undergone strict quality inspection to ensure product performance and stable data output. - The product is packed in an anti-static bag, and the two products are buckled to ensure that the pins are not bent. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.7 out of 5 stars 85 Reviews | ## Images ![10pcs SN74AHCT125N Quadruple Bus Buffer Gates 3-State Outputs。 - Image 1](https://m.media-amazon.com/images/I/71nNHK2tmNL.jpg) ![10pcs SN74AHCT125N Quadruple Bus Buffer Gates 3-State Outputs。 - Image 2](https://m.media-amazon.com/images/I/717lUSSVWtL.jpg) ![10pcs SN74AHCT125N Quadruple Bus Buffer Gates 3-State Outputs。 - Image 3](https://m.media-amazon.com/images/I/719oBZnI1+L.jpg) ![10pcs SN74AHCT125N Quadruple Bus Buffer Gates 3-State Outputs。 - Image 4](https://m.media-amazon.com/images/I/71LlLy1NqYL.jpg) ![10pcs SN74AHCT125N Quadruple Bus Buffer Gates 3-State Outputs。 - Image 5](https://m.media-amazon.com/images/I/81RXY4IN53L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fixed my WS2812 LED flicker *by R***K on March 6, 2026* Picked these up while troubleshooting a WS2812 LED strip that was flickering when driven from an ESP32.
