Power the 74AHCT125 with 5V and it will cleanly detect 3.3V logic inputs — particularly useful when connecting devices like Teensy 3.x to NeoPixels or other 5V peripherals.\n\nTo use, apply 5V to VCC, connect GND, and tie the /OE (output enable) pins low. Data enters on the A pins and exits on the corresponding Y pins. You can also power it at 3V to safely read 5V logic inputs for stepping down voltage levels.\n\nKey Features\n\n\nQuad Buffer/Level Shifter – Four independent channels\n\n3V to 5V Shifting – Optimised for upshifting 3.3V logic to 5V\n\n5V to 3V Capable – Power at 3V to safely read 5V inputs\n\nOutput Enable – Individual /OE pins for each channel\n\nDIP Package – Breadboard and perfboard friendly\n\n\nIdeal For\n\nConnecting 3.3V microcontrollers to 5V NeoPixels/WS2812B\nRaspberry Pi to 5V peripheral interfacing\nMixed-voltage digital circuits\n\n\nResources\n\nDatasheet (PDF)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8988,"title":"Default Title","sku":"AF-1787","price":3.08,"on_sale":false,"in_stock":true,"available_quantity":108,"option1":"Default Title"}]}
