74LVC1T45 Level Translator

The 74LVC1T45 Level Translator is a logic IC in the LabWired part catalog. Its catalog type is 74lvc1t45. It connects to the MCU over GPIO. The catalog gives a supply range of 1.65–5.5 V. It has 7 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

From the catalog: Single-bit bidirectional level translator (core/configs/devices/74lvc1t45.yaml), 4 ns. ⚠️ THE TRANSLATION IS A NO-OP: VCCA/VCCB is the reason this part exists and this engine has no voltage domains, so only the direction and the isolation are simulated — a board a missing translator would break still runs here.

How to simulate the 74LVC1T45 Level Translator in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the 74LVC1T45 Level Translator (catalog type 74lvc1t45).
  3. Connect VCCA, VCCB and GND to the supply and ground of the board. Use a supply inside the catalog range of 1.65–5.5 V.
  4. Connect A, B, DIR and OE as your circuit needs.
  5. Run the firmware. It drives and reads the pins of the part, and the device model responds on those pins.
