Designed for reliable logic level shifting and bus driving, it operates efficiently across a wide temperature range (-40°C to 85°C). Packaged in a DIP-14 form factor and rigorously quality tested, this 10-piece set is ideal for professionals seeking stable, flicker-free data signals in microcontroller and LED projects. ## 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 with WLED - I've only used one so far, but works well with my WLED project. ## 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 | |---------------|-------| | Manufacturer | Bridgold | | Part number | bg-135 | | Item Weight | 11 g | | Package Dimensions | 12.8 x 6.7 x 1.3 cm; 11 g | | Manufacturer reference | bg-135 | | Batteries included? | No | | Batteries Required? | No | ## Images ![10pcs SN74AHCT125N SN74 Quadruple Bus Buffer Gates with 3-State Outputs IC DIP-14. - Image 1](https://m.media-amazon.com/images/I/71nNHK2tmNL.jpg) ![10pcs SN74AHCT125N SN74 Quadruple Bus Buffer Gates with 3-State Outputs IC DIP-14. - Image 2](https://m.media-amazon.com/images/I/717lUSSVWtL.jpg) ![10pcs SN74AHCT125N SN74 Quadruple Bus Buffer Gates with 3-State Outputs IC DIP-14. - Image 3](https://m.media-amazon.com/images/I/719oBZnI1+L.jpg) ![10pcs SN74AHCT125N SN74 Quadruple Bus Buffer Gates with 3-State Outputs IC DIP-14. - Image 4](https://m.media-amazon.com/images/I/71LlLy1NqYL.jpg) ![10pcs SN74AHCT125N SN74 Quadruple Bus Buffer Gates with 3-State Outputs IC DIP-14. - Image 5](https://m.media-amazon.com/images/I/81RXY4IN53L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fixed my WS2812 LED flicker *by R***K on 6 March 2026* 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.

My breadboard has never been happier. *by A***T on 3 June 2026* Bought these Bridgold SN74AHCT125N quad bus buffers expecting them to do the usual boring logic thing. Instead, they showed up ready to party. Clean 3-state outputs, solid DIP packaging that fits my breadboard like it was made for it, and they handle my slightly chaotic microcontroller buses without breaking a sweat (or smoking). Zero floating pins, zero attitude — just reliable buffering that keeps everything nicely isolated when needed. I've already burned through half the pack on various projects and they're still going strong. If your circuit needs something that knows when to speak and when to shut up gracefully, these are the chips for you. ## Frequently Bought Together - Bridgold 10pcs SN74AHCT125N SN74 Quadruple Bus Buffer Gates with 3-State Outputs IC DIP-14. - ElectroCookie Prototype PCB Solderable Breadboard for Electronics Projects Compatible for DIY Arduino Soldering Projects, Gold-Plated (5 Pack + 1 Mini Board, Matte Black) - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/638968909-10pcs-sn74ahct125n-sn74-quadruple-bus-buffer-gates-with-3-state](https://www.desertcart.co.za/products/638968909-10pcs-sn74ahct125n-sn74-quadruple-bus-buffer-gates-with-3-state) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-31*
