Logic Gate Diagram Maker

A logic gate diagram shows how Boolean logic is implemented in hardware — inputs flow through gates (AND, OR, NOT, etc.) to produce outputs. You need one when designing digital circuits, explaining combinational or sequential logic, or documenting a safety interlock or control system.

The generator supports all standard combinational gates (AND, OR, NOT, NAND, NOR, XOR, XNOR, BUF), output buffers (TRISTATE_BUF, OPEN_DRAIN, SCHMITT), flip-flops (DFF, JKFF, SRFF, TFF), latches (LATCH_SR, LATCH_D), and complex blocks like MUX, DEMUX, DECODER, and COUNTER.

Yes. Describe the change in the chat — for example, "add an active-low enable input" or "group the output stage into a separate module" — and the AI updates the circuit and its labels in seconds.

Yes. Export as PNG from the editor toolbar, or copy the diagram to paste into lab reports, design documents, presentations, or datasheets.
