Wokwi cd54hct30 Chip

This is a custom chip for Wokwi. It implements the cd54hct30 IC.

Description

The cd54hct30 contain single 2-input Positive-OR gates. Each gate performs the Boolean function of Y = NOT(A . B . C . D . E . F . G . H) in positive logic.

Usage

To use this chip in your project, include it as a dependency in your diagram.json file:

  "dependencies": {
    "chip-cd54hct30": "github:wokwi-custom-chips/cd54hct30@0.1.0"
  }

Then, add the chip to your circuit by adding a chip-cd54hct30 item to the parts section of diagram.json:

  "parts": {
    ...,
    { "type": "chip-cd54hct30", "id": "chip1" }
  },
