74LVC245 - Breadboard Friendly 8-bit Logic Level Shifter
We have ✅ 2 available of the AF-735 in our Sydney warehouse. An extra 100 units available with a short lead time.
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
