## Description

An 8-bit logic level shifter in a breadboard-friendly DIP package. 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. Even 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. Key Features 8-Bit Level Shifting – Eight independent unidirectional channels Wide Voltage Range – VCC from 1.8V to 3.3V, inputs tolerate up to 5V Output Enable – OE pin to enable/disable all outputs Direction Control – DIR pin selects A→B or B→A translation DIP Package – Breadboard and perfboard friendly How to Use Connect VCC to your target logic level (e.g. 3.3V) Connect GND to ground Tie OE (output enable) to ground to enable the device Tie DIR (direction) to VCC 5V signals on A pins appear level-shifted on B pins Note: This chip is for digital signals only. It does not work with I2C, 1-Wire, or analogue signals. Resources Datasheet (PDF)
