The 74HC05, because of its open-drain architecture, can only actively pull a signal Low (acting like a switch connected to Ground). When the chip wants to output a High signal, it simply disconnects, leaving the pin floating. To actually get a High signal, you must physically wire a pull-up resistor from the output pin to your positive voltage supply. This unique trait allows you to physically wire the outputs of multiple 74HC05 gates together onto a single wire without causing a fatal short circuit. If any one of the gates turns ON, it pulls the entire shared line Low.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eKey Features
