74HC04 Hex Inverter

The 74HC04 Hex Inverter is a logic IC in the LabWired part catalog. Its catalog type is 74hc04. It connects to the MCU over GPIO. The catalog gives a supply range of 2–6 V. It has 14 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: Hex inverter (core/configs/devices/74hc04.yaml), 7 ns. No enable: every Y always follows its A.

How to simulate the 74HC04 Hex Inverter in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the 74HC04 Hex Inverter (catalog type 74hc04).
Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 2–6 V.
Connect A1, A2, A3, A4, A5, A6, Y1, Y2, Y3, Y4, Y5 and Y6 as your circuit needs.
Run the firmware. It drives and reads the pins of the part, and the device model responds on those pins.
