The 7405 is a hex inverter with open-collector outputs, meaning it contains six independent NOT gates. Each NOT gate inverts the input signal; a high input results in a low output, and vice versa. The open-collector output requires an external pull-up resistor to define the high logic level. This feature allows for wired-AND logic implementation and interfacing with circuits operating at different voltage levels, a valuable feature in many applications. Here is an example showcasing what you might find in the datasheet related to voltage levels:
| Parameter | Symbol | Min | Max | Unit |
|---|---|---|---|---|
| Supply Voltage | VCC | 4.75 | 5.25 | V |
| Input Voltage High | VIH | 2.0 | - | V |
