The 74LVC245 converts between 3.3V and 5V logic levels, making it easy to interface modern 3.3V sensors and peripherals with 5V microcontrollers like Arduino.\n\nEven when powered at 1.8V, the chip safely accepts up to 5V signals on its input pins and converts them to the lower voltage on the output side. It handles 8 channels of unidirectional digital signals — ideal for SPI, serial, and parallel bus interfaces. Note that it does not support bidirectional protocols like I2C or 1-Wire.\n\nKey Features\n\n\n8-Bit Level Shifting – Eight independent unidirectional channels\n\nWide Voltage Range – VCC from 1.8V to 3.3V, inputs tolerate up to 5V\n\nOutput Enable – OE pin to enable/disable all outputs\n\nDirection Control – DIR pin selects A→B or B→A translation\n\nDIP Package – Breadboard and perfboard friendly\n\n\nHow to Use\n\nConnect VCC to your target logic level (e.g. 3.3V)\nConnect GND to ground\nTie OE (output enable) to ground to enable the device\nTie DIR (direction) to VCC\n5V signals on A pins appear level-shifted on B pins\n\n\n\nNote: This chip is for digital signals only. It does not work with I2C, 1-Wire, or analogue signals.\n\n\nResources\n\nDatasheet (PDF)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13402,"title":"Default Title","sku":"AF-735","price":2.92,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
